Zabbix Server is crashing after running for some days. This system has very low workload, it's required server performance is about "10"...

In the "messages" and "syslog" protocols, the following line is written:
Jan 13 07:16:34 zs1 vmunix: [385248.330790] modprobe[4884]: segfault at b78d922c ip b76e4748 sp bf99b9a0 error 4 in ld-2.13.so[b76d6000+1c000]

The stack trace of the server log is attached as "zs1-zabbix-server.log". The object dump from the server binary is attached as "zs1-objdump.gz".

I've checked the installed binaries with "debsums" where all is reported ok. The "lighttp" webserver and MySQL database are running fine.
