I have a couple of followup questions for you: 1) Did it happen to all the patched servers or just to one of them? Moreover, did it happen right after the deploy/upgrade or after a long time? I am asking because I don't know your settings and it would help to know the scale of the impact to the 1500 servers. 2) Have you checked the scoreboard in mod_status when the issue happened by any chance? It would be useful to know the status of the workers when they reached AH00485. It could be an occurrence of bug 53555 or maybe a new behavior of mpm_event after this patch.. Regards, Luca
