Could you please help me to understand why asterisk is crashing so often. Sometimes it can work normally for 1 week - but sometimes it can crash 3-4 times per day.

I tried to load core dumps with gdb - and this is what I received:

# gdb asterisk core.dump
…
Loaded symbols for /lib64/libnss_dns.so.2
Reading symbols from /lib64/libgcc_s.so.1…(no debugging symbols found)…done.
Loaded symbols for /lib64/libgcc_s.so.1

warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffffdff6000
Core was generated by `/usr/sbin/asterisk -f -vvvg -c'.
