Problem with crons and command line php

[jonvfelosi]

On all of our users who are running crons that execute php, probably other binaries are getting out of memory errors, even after raising memory quite a bit it still happens.
Our whmcs crons and everything quit working so here I am.

what can be done here?

You can disable LVE in cronjobs for now, until the issue is fixed.

Though I don know what is causing it.

Could you post content of /proc/lve/list

I see users with 1GB hitting the limit from time to time, yet user with 512MB limit hitting it quite a lot of time.

Is it possible that they actually reach the limit. Single PHP process can easily take up 100-200MB, so if multiple processes are spawned it can use that much memory.

Few things you can do:
1. Try setting memory limit to 0 (means no limit)
2. Increasing memory limts, and seeing if they are still hit
3. Check lvetop while running cron jobs (or same command as cronjobs, under user, within lve, via lve_wrapper, or our pam lve module)
4. Using top to check.

Or if you would like -- contact our support or me direct at iseletsk@cloudlinux.com -- and I would be happy to check you system, and see exactly what is going on.

email sent, thanks Igor

Igor, has this problem been resolved? i.e. have you made it so that cronjobs are ignored? Or what else would you suggest?

[iseletsk]

It was resolved. Make sure you have set virtual memory limit high enough.
