[HM666]

Do you have an events mod installed? If so then I would suggest that you go to that thread and post there for help. That is most likely due to a plugin or mod you have installed on the site.

[kh99]

cron.php process cause high cpu usage and it seems loop problem and does not finish
i have to kill this process each time.
please help me

You could try somehow narrowing it down to which scheduled task is causing the problem. That looks like a loop that's reading data from a socket, so maybe something that makes a network connection, in case that helps. It might help if you know about what time or times during the day that he problem starts, then compare that to your scheduled tasks.

@hm666:
no, i dont know this mod and i have not installed this

@kh99
everything was ok and i did not installed anything special
recently i just updated my php and mysql to 5.6.23
may this cause such problem
this process cause high cpu usage for my server please help me find the problem
this cron will run automatically 4 time a day and if i dont kill it all 4 crons will be run together with same info as below:

i can't get it's running time as apache trace not giving me time/date in below info :(

What mods do you have installed? List them or take a screenshot and post the image here as an attachment or upload to an image hosting site and provide a link to the image. Its more than likely a scheduled task (or plugin in a mod that adds a scheduled task) which shows events (Calendar maybe) OR Polls from the looks of it.

Unless someone comes along whose ran into this issue before, I myself and others can't simply tell from code being pasted all the time, its not always possible to help that way unfortunately so the more information you can give, the better.

@kh99

I suppose it could. What version of vbulletin do you have, and what version of php? If you're using a php version that is too high, you'd probably want to take care of that an see if it fixes the problem.

this process cause high cpu usage for my server please help me find the problem

I don't see anything that runs 4 times a day by default, but I guess if a scheduled task fails to complete it might be scheduled to run again, I'm not sure.

Have you looked at the scheduled task log? Maybe you can edit each scheduled task and set "Log Entries" to Yes. It looks like most tasks log at the end, so if you turn loggin on for all of them you mgiht be able to figure it out by seeing which one is not being logged.

refer to the operating system functions poll() (http://unixhelp.ed.ac.uk/CGI/man-cgi?poll+2) and recvfrom() (http://unixhelp.ed.ac.uk/CGI/man-cgi?recvfrom+2) which have to do with reading from sockets (network connections), so the problem doesn't necessarily have anything to do with vbulletin events or polls.

If the problem still exists after upgrading to vb3.8.9, I would look at things that make network connections, like sending emails (birthdays?) or getting RSS feeds (if you have any of those defined).

I don't know, but you could try disabling individual feeds (if you have more than one), and maybe you can narrow it down to one causing a problem.
