Re: MySQL Crash

MySQL is installed on a Virtual Machine and has a setting of "unlimited CPUs". So I am guessing that it is using all 4 CPUs of the host server (plus "cat /proc/cpuinfo" shows 4 CPUs).

When setting the "innodb_thread_concurrency" to a value different that 2 I get errors on Plesk saying it cannot read from the database. So far I have found no other solution than to leave this value as it is.

I will try lowering the "query_cache_size". Is 64M a good value?

I have found some posts on the Internet mentioning that if a query is performed on a corrupted table, then MySQL crashes. How can I log all the performed queries so I can see if that is the case? I should mention that I have run a "myisamchk (-r)" on all my databases.
