Problem

Today I logged into my OPNsense dashboard and saw 99% memory and swap usage. I found out that there were 1231 php processes running, each using more than 60 MB of RAM.

A reboot of course fixed the issue, as after reboot only 8 php processes are running, but this can happen again I guess?

How can there be so many processes? Isn't there any limit set how many php processes can be spawned? I kind of know the configuration of php-fpm, there you can provide a maximum number of processes to fork. But it seems OPNsense core is not using php-fpm, but php-cgi.

I would be very happy about any help!

Never experienced these problems before...

ps faxd | grep php ?

Yeah now it's only the 8 processes. Will keep an eye on it and reply if it rises again...

So as it never happened again, I think we can close this issue now.
