Errors logging into GUI

Hello All,

New install FreePBX Just completed setup and everything was humming along nicely. Last thing I was looking at the options under Follow Me. Didn’t apply any updates or anything, nor did I restart. Now getting the error below immediately at login to GUI.

exec(): Unable to fork [locale -a]

Any ideas?
Thanks, Steve

You are out of system resources

OK, thanks. I will reboot tonight, after hours. This is a pre-built appliance (not Sangoma). Any idea if this could be a config error or something deeper?

Reboot cleared it up. Prior to reboot, the memory usage was at 93% and swap 100%. Now to figure out why…
