Server crashes silently

[SweetyWolf]

My CentOS 7 x64 server keeps crashing silently every 30 minutes or so. There is no any suspicios line in server.log. Every crash log is the same, except for memory addresses (values like 0x7fd471d3b90c).

Kern.log:

	Oct  3 17:25:26 dericstar kernel: [  697.531074] mta-server64[1318]: segfault at 7ff17128f4a0 ip 00007ff289a7279c sp 00007ffe67cbc2a8 error 6 in libc-2.19.so[7ff289921000+1ba000]
	

Typical crash log:

	MTA:SA Server v1.5.4-r11428-release crash report.
