Issue Apache restart failing

Rincewind

New Pleskian
I'm having an issue with one of my Plesk servers with apache. Its CL 6.10 & Obsidian. Occasionally when Apache is restarting, which it seems to do a lot, around every hour or so, It is failing to start again until the next restart gets sent.

I can manually recreate what I'd assume is this issue with "service httpd restart". Most of the time it works, but about 1/4 of the time it fails to start as something is is already listening on port 80. If I'm quick with running netstat when this happens, httpd is still listening on port 80 for a second or 2 after an apparent successful stop! It eventually stops and the next attempt at starting works. service httpd graceful also just turns off apache and leaves httpd listening

I've done:
  • updates,
  • plesk repair and restarted the server
  • # apachectl -t = Syntax OK
  • There are no duplicated Listen entries in .confs
  • Graceful restart is disabled and restart interval is 3600


I'll post a chunk of httpd error log, essentially you can see the restart and then nothing for some time, until I guess another restart starts Apache.


Code: 
# service httpd restart
Stopping httpd:                                            [  OK  ]

do you have nginx installed?
if yes do:
Code: 
# plesk sbin nginxmng -d && plesk sbin nginxmng -e


this because apache does try to bind to 80 and something is already bound to 80 (probably nginx)
in such case apache should be on 7080 and not 80

Thanks, though I dont think its that as its not something else bound to port 80, it appears to be httpd already on it. If I do a netstat when this happens httpd is what is listening on port 80 for a few seconds after it should have stopped, not nginx. I guess either it's failing to stop it correctly, or its starting too early and failing when the other start is attempted.

I have a cronjob script to check if apache is up and restart if not, but thats failed on occasion and its only started when I've started apache from the CP, I need to check what the error log was saying at that time though. Oddly restarting from the CP doesn't seem to crash ever, while cmd line does, what's different?
