Hibernated notebook with open connection over VPN. After wakeup from hibernation the VPN was not active so the WinSCP could not re-establish the connection. The VPN adds new virtual interface when activated and removes it when the VPN is deactivated. Maybe the WinSCP was trying to re-eastablish connection at the same time when the VPN was disabling the virtual interface?

Invalid access to memory - System::FillChar

WHEN WinSCP is running with the Network turned OFF, it constantly pops up a dialog box to say it can't reach its destination, and that it is retrying in ___ seconds. This appears to cause some resource leak, which after 2-3 nights (cumulative) of running with the network turned off finally leads to this crash.

At night, I use Control Panel to turn off networking because Firefox, (with/when many, many tabs open) eventually starts thrashing page file swapping, eventually lead to an unresponsive system.

Even without finding & plugging the resource leak, this could be improved by adding a PAUSE button to the pop-up saying that it can't reach its destination. Hitting the PAUSE button could freeze retrys until I hit the CONTINUE/UNPAUSE. I believe it likely that pausing the retry cycle will pause the resource leak. ALTERNATIVELY, start backing off the retry time as failed retrys accumulate. This will also slow down the resource leak.

Forth time - Invalid access to memory - System::FillChar

Remains consistent with my prior detailed report: On Win 10 Pro, using Control panel, I turn my computer's networking off at night. (With Firefox Latest, I have hundred & hundreds of tabs open. After a while, 6 - 10 hours, Firefox starts thrashing to disk: Now the pagefile, and previously session backup. With the network on, the computer sometimes becomes so unresponsive, that only a hard power off will reset it.)

WinSCP seems to crash when left running with an open session after two or three days (and nights WITH the Network OFF - my daily schedule is varied enough that it is likely the major factor in the variable timing to the crashes.

When the network is shut down while WinSCP has an open session, WinSCP pops up a dialog box to say the network is down, then it counts down about 10 seconds and retries. I suspect that there is some sort of resource leak with this box popping up. OR it may be a resource leak IFF a Race-Condition fails - once Firefox starts thrashing to disk, the computer is often momentarily unresponsive (i.e. mouse freeze, or keystrokes lost or delayed 5 - 10 seconds.)

I'm sorry, I missed your email of a few days ago asking me to down load a debug version
<link to private build removed by admin>

Is that link to the current debug version I should use, or is there a newer version I should load?

Re: 3rd time in 10 Days -- Invalid access to memory - System::FillChar

In the last 10 days, WinSCP has now crashed for the third time with this error. The following describes the consistent circumstances that I believe (/am guessing) lead to this crash.

On Win 10 Pro, I'm running Firefox latest with about 6 windows open, and collectively hundreds and hundreds of tabs open. As Firefox runs this way, it continues to increase its use of system resources until the pc barely crawls.

To fight this Firefox problem, at night, I disable networking (via Control Panel > Network & Internet > Network Connections), and in the morning (after Firefox has all night to properly record/backup the current session), I use Resource Monitor to kill the primary Firefox task (almost always, the Firefox task with the most threads.) Once everything settles down, I restart Firefox (before reconnecting the network.) Then once Firefox has a chance to open all the tabs - and times them out because it can't connect - I re-enable the network. (This seems to keep Firefox better behaving for longer, as the tabs that never got reloaded don't seem to aggravate Firefox's drift to resource consumption.)

WHEN WinSCP crashes, it has been left on over night, with an active connection to another computer WHILE the Network has been Disabled. (When WinSCP is running, connected to an outside computer, and loses network connectivity, it constantly pops up a dialog box to say it has no connectivity, then counts down and retries the connection. This cycle goes on all night until the network connection restarts.) On the days when WinSCP hasn't crashed overnight, once the network is reconnected, it continues where it left off the night before with no problems - I don't restart it. (But since I've not seen WinSCP crash two days in a row, the crash may require the accumulations of 2 or 3+ nights of being shut off to cause the crash.)

I guessing that something in WinSCP's Alert/Retry loop for a failed network connection has some sort of (Probabilistic?) resource leak - perhaps exacerbated by the resource load Firefox presents (even with out network access, Firefox is constantly backing stuff up to disk.)

While the above does not produce a hard deterministic fail, 3 times in 10 days seems like a lead to investigate. As a guess, maybe there is a race condition that Firefox interferes with, causing the resource leak only sometimes. Then on nights where the there is enough accumulated leakage (perhaps from the Alert/Retry loop) WinSCP actually crashes.

(A further note on Firefox's wayward tendencies: I use Firefox for a fair bit of research every day, and it hits a number of sites with javascript ad rotaters that constantly try to hit the network for their next load.)

I hope this helps. Contact me if you wish. Please start the email subject link with "WinSCP" as I get a lot of junk email, and generally visually scan the start of the subject line for keywords.)

Invalid access to memory - System::FillChar -- 2nd time (but several in between w/o problem...)

On Win 10 Pro, using Control Panel > Network and Internet > Network Connections, at night I turn off the only network connection (Hardwired Ethernet.) (I do this most every night now as Firefox seems to develop issues if left alone for long periods of time.)

This is the second time I've encountered this issue in this past week -- turn off the network connection at night, come back to WinSCP crashed. However there were several nights in between without problem. (My computer is an HP EliteDesk SFF with an i7 & 8 GB RAM.)

Invalid access to memory - System::FillChar

This bug is a first encounter. I use WinSCP (now on Win10 pro) to access files on a nearby Linux machine. Generally when accessed, the files are opened in notepad++. I have been using this setup for months (and similar: Win 8, remote Linux of various flavors, and older notepad++ for over a decade.)

Recently (about a week ago) I started disabling the network (via Win 10 Control panel) at the end of the day. (This is to minimize what appears to be Firefox eventually thrashing session backups to disk when left running unattended over night.)

Both Firefox and Windows updated some time last week, and I started disabling the network at night just a few days before that (previously, I had often disconnected the network cable on the laptop I was then using.) Last night WinSCP was left running with I think just one file open (for auto update back to Linux of any file changes by Notepad++.)

Without having made specific notes, I'd say that, per the above, WinSCP was left open every night for the last week, with one or more files open for auto updating back to Linux (and the network Disabled via the Win Control Panel.)

This morning, I found the Win 10 machine with a popup window alerting to this bug crash. As best I recall, in well over a decade of my using WinSCP, this is the first crash I've encountered.

I hope the above description is useful, thanks for a very useful piece of software!

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

Invalid access to memory - System::FillChar

System was left in an idle state. Not in standby, but my windows session was locked. The SSH Agent which provides credentials for the currently logged in session closes down when the system is idle, which sometimes causes WinSCP to poop itself. Not consistently, but it does happen once or twice a week.
