-----Ursprüngliche Nachricht----- Von: Hullen@xxxxxxxxxxx > Is there any line before 13:30:07 which shows more information? Hi Helmut, nothing special before 13:30:07. I guess the problem is still some bug in sgLog.c. I just tried to rebuild squidguard 1.4 with the additional 2 patches http://squidguard.org/Downloads/Patches/1.4/ just to be sure but same results. 2012-08-27 12:01:03 [5902] overflow in vsprintf (sgLogError): Success 2012-08-27 12:01:03 [5902] Going into emergency mode Durring the midday, this happens every few minutes... This is really a showstopper right now for us :( Stefan
