2. Crash happen randomly
3. Asterisk is used as gateway (pjsip). It's also doing some number translation (fastagi script)  and adding costum SIP headers on outbound channels
We are using default configuration files.

Can you execute:

/var/lib/asterisk/scripts/ast_coredumper --tarball-coredumps --no-default-search

To create a tarball including core dump and binaries for examination? If you can make it available for download you can then email asteriskteam@digium.com with a link to download it.

after execution i receive this: cp: cannot stat '/usr/lib64/libasterisk*': No such file or directory

Have you installed Asterisk in a custom location at all on the system?
