@mechanical_fish yes and it was a mysql installation. Weird things happen with all systems once you push them up to the edge of performance both of the hardware and interconnections between servers.

Slow interconnect between servers caused me headaches in the past with mysql for replication. Shared switched did the same. Problems with locks under high contention did the same. Problems with the client libraries the same. In fact all storage systems have similar problems and pain. Some are just more battle tested than others.
