My server crashes eventually in about 1-2 days.
If it's my plugin it usually says something along the line with "sourcemod.dll" for the crash dump, but I haven't had a luck trying to find where it's coming from:

This happens regularly and I can't f ind a reason for it. Happens in different maps, so it's not map specific.
