Multisite database keeps crashing

Our database keeps crashing. It's an almost everyday occurrence . We keep getting this error message:

[Fri Aug 05 13:16:23 2016] [error] [client] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

Usually, repairing the wp_sitemeta table fixes the problem but sometimes I have to repair wp_options tables for individual sites. I've had to reboot MySQL a couple of times as well.
