My Mariadb server always crashing on one large database, but problem must be deeper because I cannot even do mysqlcheck for all databases beacase server is losing connection according to crash. One database was recovered from frm and ibd files, maybe there is some corruption there but I cannot even now dump.
Forcing recovery of table does not work :/ Spent two weeks fighting that problem that's why I decided to post it here maybe you can understand what is going on and how to at least dump the tables.

I attached relevant syslog file and my cnf file.
