my-p0 MySQL server out of memory

Print Friendly, PDF & Email

Due to 2 issues, inadequate memory allocation and the replacement of a secondary disk in the block level replication mechanism (DRBD), the main production mysql server suffered an outage between ?11:53 and 12:17 today.

The length of the outage what exasperated by the replication of the disk. I will consider increasing the memory usage of the underlying Xen host to help increase the performance of this process.
