Not a blocker, doesn't affect absolutely all users.

I installed the newest version and now I have this problem also. FileZilla crashes around every 10 Minutes...

[Tim Kosse]

Please attach the latest crash dump located at %LOCALAPPDATA%\CrashDumps

[Markus]

I'm sorry, but there are no crashdumps. FileZilla-server.exe ist registered for crashdumps but there are none...???

I have the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting\LocalDumps\filezilla-server.exe
With value (dword) DumpType = 1

I only see the error in the event log and the service is not running any more...

You need to check in the %LOCALAPPDATA%\CrashDumps of the Windows account the server service is running under, SYSTEM by default.

Not in front of a Windows right now, if I remember correclty it's under c:\windows\system32\config\systemprofile by default.

thanks, in this folder there are crashdumps... See attachment

[Markus]

Can you please delete the attachement as soon as you downloaded it...

[Tim Kosse]

Unfortunately the crash dump was inconclusive.

What is needed is a dump from a build with debug symbols.

1. Download https://filezilla-project.org/nightlies_server/2022-07-26/win64/FileZilla_Server_debug.tar.bz2
2. Make sure the server is not running.
3. Extract the contents of the tarball into FileZilla Server's installation directory, overwriting the old executables and libraries.
4. Afterwards start the server
5. Once it crashes, submit the fresh dump.

[Markus]

I uploaded a Dump created with your debug version. Please delete again after download...

[Tim Kosse]

Thanks for the dumps, I managed to reproduce the issue.

[Tim Kosse]

The bug should be fixed, please try this build: https://filezilla-project.org/nightlies_server/2022-07-27/win64/FileZilla_Server_1.5.0_win64-setup.exe

[Markus]

Since the installation of the new version there was no crash any more.

Thanks a lot for your quick help!
