I don't think so. Over the last year or so, we've seen a lot of problems with MySQL using too much memory for no apparent reason, and sometimes running out of memory and crashing. (This is not something that's just been happening in the last couple of months.) I wasn't able to find anything that might cause this, but I did not consider that someone would create 4GB of MEMORY tables.
From what I remember, there were a lot of various reasons why ts
crashed. Just during last month I've started receiving messages "cannot allocate XXX" during processing.
Did you meanwhile know it worked in 24x7-like mode during last year and sometimes two bots were working in parallel?
