Hello there! I've gone back and forth with the cPanel techs (ticket 196335) on a really oddball little issue. Many nights (generally about 2 out of 3 nights) since the cPanel 11 update, httpd has failed just after upcp ran and I get an email from the chksrvd to that affect. Apace always came back up OK, but I still wanted to figure out what was going on incase it decided to *not* come bac up. Nothing in the upcp logs should've been causing Apache to restart. Originally, we thought it might have been a resource issue (despite my server having 2gb of RAM and a plenty fast CPU), so we moved the nightly backup process so it was further away (couple hours). that didn't help. We made sure Perl was fully up-to-date, and that dependent libraries I was using were up to date. No help. We recreated the httpd entry for chksrvd, no help. We found and fixed the bug that was occuring in current for a while, no help. Load was never up high as my load checking alarms never sent me anything. It would stop for a while (a week or so) and then start up again randomly. And chkservd.log would never show that httpd would be attemped to restart. So we turned off upcp for a few days, and while httpd didn't fail, chksrvd did fail one of the nights of the 5 or so we left it off. Turned it back on, and then the 2nd night, httpd failed again. The cPanel techs were stumped. So last night, after having this ticket open and closed for a couple months now, cPanel had a level 2 tech watch it overnight. After the overnight watch: All my ports appear to be open properly: tcpin:20,21,22,25,53,80,110,143,443,465,953,993,995,2082,2083,2086,2087,2095,20 96 tcpout: 20,21,22,25,37,43,53,80,110,113,443,587,873,953,2087,2089,2703 udpin: 20,21,53,953 udpout: 20,21,53,113,123,873,953,6277 And I went through and whitelisted my server's other IP addresses just to see if that helps. To confirm that csf is the problem, without turning the thing off entirely, is there away to have it turned off for just a couple hours during the couple hours when the problem usually occurs? Has anybody else ran into this? Thoughts, ideas?
