Re: How to control the php stand-alone process
Hello "Rudi" <firstname.lastname@example.org>,
Thanks. My question is, since there are many stand-alone php scripts
frequently activated and, hopefully, gracefully exit in my system, I,
as the superuser, have to allocate reasonable resource for them to avoid
unpredictable situation to cause resource exhaust. Well, I can use
sysctl command to give reasonable resource of the user running php
stand-alone scripts, however, if there are some problems which result
into some php processes staying in the system for too long. I have to
avoid that situation, because this could cause a lot of php processes
hanging in my system, some of them should have been running for weeks.
I know top or ps can get the status of them and I can of course make any
changes of them. However, I just want to know a hard limit control to
the stand-alone scripts. Even when php scripts use system call and
therefor can't be restricted by its native timeout function, I still
can make a system-wide restriction and timeout control of them.
