I am continuing to have problems with sitemeta and options tables

The problems seem to never end. I keep having intermittent problems just trying to go to the plugins page in network/admin. Sometimes I can get there, sometimes not. If I get there sometimes I am able to update plugins sometimes not. I have NO users and no traffic. Does any one have an idea of why this type of issue could be occurring? It results in memory issues but that is NOT the problem, that is a symptom.

Error log is attached.

thanks for any help.
