The libc upgrade breaks the smtpd and perl - undo the upgrade. Or open a 
support request at debian, hope they can help.

Betreff:        [Assp-user] Since APT Update Kernel Oops regarding to ASSP 

/ Crash



Hi, 

i run ASSP Version 1.10.0 on a Debian 6.0.10 ( 2.6.32-5-686-bigmem ) for a 


while with no problems at all. but since the last apt update assp crashes 
and i retrieve kernel Oops.

the apt update was:

assp starts up normaly. when the first connection ( nevermind if its a 
mail connection or web backend of assp) the error occurs and assp breaks 
down.
the assp log doesnt show any problems (neither when the crash / Oops 
starts). it is free of any errors or such. 

the kernel oops crash log (kernel.log) is:

what i can conclude from the log is that it is assp (from PID and Process 
Name). Can anyone help me to resolve my problem or at least have a hint. 
thank you in advance.

with kind of regards,
