There seems to be a memory leak in WinSCP: when downloading large files from a server, the memory usage constantly increases in task manager (the same happens when downloading several medium sized files; perhaps also with small ones but difficult to detect in this case). From a memory usage under 20 MB in normal conditions (connected to server), the memory usage increases to several hundreds of MB, about 6 times the size of the transferred files during my tests. Also, the CPU is heavily used (around 100%). I tried with several servers, but they all run the same OpenSSH server software. Is this a bug, or something wrong with my configuration?
WinSCP versions tried: 4.1.9 (build 416) and 4.2.3 (build 494).
Session protocol = SSH-2
SSH implementation = OpenSSH_4.7p1 Debian-8ubuntu1.2
Encryption algorithm = aes
Compression = No (does the same with Yes)
File transfer protocol = SFTP-3
Used GUI, Commander mode.
OS: Windows XP, SP3
