Thread:Project:Support desk/Mediawiki 1.22+ Causes two of my servers to hang indefinitely./reply (11)

I have 1.22 installed with no issues. That's really strange.

this commit mentions that If $wgPhpCli is not set to an actual path or safe mode is on, then the old code will be used.

You may try to set $wgPhpCli to an empty string to use the old running job system until this issue is investigated an addressed.
