How to deal with distcc task time limit?

[gentoo_ram]

Been compiling KDE and the Plasma workspace for my RPi 5. There are a couple glitches, but mostly it's working. I find it pretty awesome given the complexity of the environment.

I have 2 RPi 5's and a RPi 4 so I've used distcc to help with compiling which mostly works. But there are a couple packages that contain complex C++ files to compile. I've noticed there seems to be a limit of 5 minutes that each distcc compile task can take. If the compile operation doesn't complete in 5 minutes the job is killed and re-distributed to another node. The problem is that some single compile operations in some packages takes more than five minutes to complete on a RPi 5. I'm forced to turn off the portage distcc feature to compile those packages or the build will never complete.

With distcc turned off the build completes. I've seen one compile operation take as much as 12 minutes for one file! I've Googled but haven't seen anything about this apparent task time limit. Before I start searching through source code, does anyone know anything about how to change this limit to something higher?

Interesting. Doesn't quite seem like the same issue but this lever might end up having the same effect. Thanks for the idea.
