EAccessViolation

Am getting this while uploading files.Not every file but several. Will upload some files and then stop. Does not seem to hang up on any particular file configuration. Has hung up on .css and .png as well as some .php files.

Can anyone explain what this error code means and how I may need to resolve it? Am running version 3.4.2 (build 197)Thank you

What about trying to upgrade? :-) 3.4.2 is more than 2 years old. Neither I remember what bugs it had.
