MEM latency issues

Hi all,

Has  anyone else out there experienced unusual behaviour when using MEM with either 12.5/6/7 VSA?

We have been having numerous latency issues including vSphere storage disconnects and the common theme appears to be linked to the MEM. On a test cluster we removed the MEM and reverted to RR and the latency (while slightly higher) seems far more stable.

With the MEM we have been having spikes in the hundreds of milliseconds causing massive timeouts with our applications across multiple clusters.

We have a job logged with HPE but so far nothing definitive other than our own testing using only RR PSP.

Keen to hear others comments.
