Cron Process Performance Hit?
« on: May 09, 2015, 10:38:34 AM »
Hey, guys... for the second morning in a row proximate to 0900CDT, site performance goes into the dumper for about 10-15 minutes. Pages take two to three minutes to turn around. After about 0915, no problem, back to normal.

I got two consecutive 504 errors at the same time.

Mike goes all Unix on us!   :D  Maybe a forum backup gets performed around that time (which wouldn't make any sense  to do at that time of the day).

We have an internal website we use at work which goes down for about 30 minutes around 1:30am.  I suspect that they do some sort of backup or reindexing at that time. But at least  the time is more reasonable (except for night shift people like me).  But since we are 24-hour operation I just have to put up with it realizing that they have to do it sometime in those 24 hours.

Geez, Pete... I've been doing the Unix/Linux thing for nearly a decade. There was no choice in the early days of networked video - Windows itself sucked so much CPU at the time you couldn't serve squat.

Anyway, you're right about daily maintenance processes. My last client griped about losing video streams at 0330 on those rare occasions they had to staff control centers overnight for weather events. "It had to be done sometime," was my usual response. That was when I reset all the camera streams to deal with memory leaks in the video server processes resulting from the constant retries on their crappy network.

I thought this forum was hosted on Windows?  If so, there wouldn't be cron.
