Hello Henning,

Thanks for your reply. Here's what has come up after a few hours:

shm55: https://pastebin.com/h9JCePmc
shm54: https://pastebin.com/Nx5xEEnA

It seems to me htable is the culprit? Are you seeing anything different? 54
has been running for 77020 seconds, 55 for 28521 (significantly less).

I'm going to turn it off until we figure something out...

BR,
George
