Steps to reproduce

  1. Execute cron.php from the command line: php -f cron.php

Expected behaviour

cron.php completes its tasks in less than 15 minutes and exits

Actual behaviour

cron.php continues to run (longest time I've let it run for is 48 hours). It does not consume many cpu cycles, however it slowly consumes all RAM available on the machine.

Too unstable to use atm #6

@LukasReschke - Is there a way to kill the cron after it's eaten x amount of RAM? I think this bug is killing baby devices such as the Pi.


I killed the task and disabled the cron job. Since it doesn't complete correctly there doesn't seem to be any point in running it in the first place.

I'm facing similar issue too, cron.php is always running, and I'm getting tons of mail from cron about that.
I use cron primary for my News application feed update. And it continues to fetch new posts. So it seems like cron.php is still doing its job.
Also, there is no related errors it my logfile.
I tried to debug this issue and run:

strace -e open -u www-data php -f cron.php

to see if some files or permissions are missing, and I got the following error repeatedly:

open("php://memory", O_RDONLY)          = -1 ENOENT (No such file or directory)

May be this will help.
