Fix Database errors (MySQL pro needed!!)
Budget: €8 – €30 EUR
Hey I'm getting errors in my database that need to be fixed asap.
Here are some error logs:
Oct 20 10:02:07 node5512 kernel: Out of memory: Killed process 314 (mysqld) total-vm:3730532kB, anon-rss:221188kB, file-rss:0kB, shmem-rss:0kB, UID:27 pgtables:852kB oom_score_adj:0

MySQL processes were killed, and since they were running that has caused the databases to crash. The high memory usage spike is caused by slow queries made to the database. MySQL queries should be executed for under a second which is the regular operation of the MySQL service. If they take more than one second, that means that there is an issue with the MySQL database or its operation. When queries stack up, they create a bottleneck in the MySQL service and the server continues to invest resources in order to complete the MySQL queries in the queue.
For the last 5 days, there have been 38 such queries generated by the database.
I have an error log you can look at.
