Question

I've had a few of my plugin users report the following error with my Plug-ins.

System.IO.FileNotFoundException: Could not load file or assembly 'System.Data' or one of its dependencies. The system cannot find the file specified.

File name: 'System.Data'

It seems to only happen with for people running FogBugz on a web server platform other than Windows, and some have noted that the same error is thrown by multiple plugins. One person claimed to have fixed it by upgrading to FB 7.2.16, but I don't see anything relevant int he release notes.

Is this a known issue with some versions of FogBugz for Unix regarding system.data?

Answer 1

This error message is totally benign and can be ignored with no ill effects. We are working to have it not show in the future. You can hide it by copying the System.Data.dll into the Website/bin directory:

[you@fogbugz ~]$ cp runtime/lib/mono/2.0/System.Data.dll /opt/fogbugz/Website/bin
[you@fogbugz ~]$ /etc/init.d/fogbugzctl restart

FogBugz for Linux runs on Mono. So obviously, the Mono DLL's are loaded. Otherwise you'd never get to the point where the program could even start to run, let alone show an error. At some point after that, though, the plug-in architecture tries to load them again, but cannot find them. Putting this DLL into the Website/bin directory makes it so the system can find the DLL, even though it does nothing with it afterward.

Answer 2

I had this problem after a reboot.

FogBugz had become slow, not unresponsive, but slow. Any query pegged the CPU. So I decided to reboot. Afterwards, I received the error. I have not upgraded or installed any plug-ins in months.

Ubuntu 8.0.4 LTS FogBugz 7.1.10

Hi,

I have this issue to. No plugin install or whatsoever, but our apache went mad today, eating too much ram, until killed.
