The server was restarted. Everything was working fine.
After about 30 hours when a reload was executed amavisd process was killed:
amavisd[6953]: segfault at 0 ip (null) sp 00007fff862bb9b8 error 14 in
perl[400000+2000]

In this example i've executed gdb with command as amavis process running.
gdb `/usr/bin/perl -T /usr/sbin/amavisd -c /etc/amavisd/amavisd.conf`
coredump

Also i tried to attach to amavis master process. But when i execute this
then gdb was killed by signal 11 (SIGSEGV)
gdb[8985]: segfault at 0 ip (null) sp 00007fff2be1cd48 error 14 in
gdb[400000+437000]

We use amavisd-new-2.8.0-8.el6.noarch.

Am i looking on the right way?
Can it be a hardware failure?

Thank you.
