Woke up this morning to find BigCloset down.
I didn’t have my load-monitoring script running on the front end because I wasn’t that worried about it. But I am now.
My htop session had died but was spiked over 21.5 when it did. For a general idea, a load of 1 == 1 Loaded CPU thread. We have a capacity of 6 threads so a load of 6 == Server is at capacity. A load OVER 6 == We’re over capacity, but if things slow down a bit, there is a chance to catch up.
As best I can tell at 3:11am Central time (4:11am eastern/my time) LogRotate ran and HUP’d all the services so that it could properly rotate the log files, and Apahce threw this error:
[Sun Feb 28 03:11:10 2016] [notice] seg fault or similar nasty error detected in the parent process
I will tweak and install my load monitoring script later. I was originally written for a situation just like this. Where we were throwing too much at a dieing server and wrote a script to watch for dead processes and high loads and kill things appropriately. We eventually fixed this by opening our Bridgewater,NJ pop.
