Yesterday the hottest day so far this summer 32C, the Data Warehouse MySQL server went haywire. Conections where dropped and database tables where partially unavailable this is a very heavy used server no time for deep debugging, so I restarted MySQL and all was normal again, for a few hours, then it really went crazy, now the entire server was affected not only MySQL was uncontactable but the network as well and I could see how new MySQL daemons tried to start up every ten seconds or so. this time I noticed Bacula, ClamAV and Symantec rtvscand was very active at the same time on production prime time, this is probably not a good idea. I never seen anything like this in the twenty years The Data Warehouse been up and running. This time I restarted the database server and now it seems to be OK again.
I have asked the guys responsible for the Data Warehouse to revise the schedules for ClamAV and rtvscan. Why both these daemons are used I do not know. A poolicy of supporters and belts?
