Launcher spikes to high CPU after running for a while (approx. an hour)

GinjaNinja32 opened this issue 9 years ago · 5 comments

I'm running launcher version 1.4.10, FTB Infinity 1.11.2, Java 8u60 on Linux. Restarting the launcher fixes it temporarily, but it comes back after around an hour of playing.

Once it starts spiking, it gets worse over time, eventually freezing Minecraft every couple of seconds by taking up the entirety of the available CPU time:

(the 9 'running' tasks are htop and 8 FTB launcher threads)

Try closing console window.

This is with the console window disabled.

Interesting. What if you start it with java -jar FTB_Launcher.jar --disable-mc-logging

If that high CPU usage is caused by something else than logging then you have found a new bug.

With --disable-mc-logging it doesn't spike.

What's going on in logging that it needs that much power?

Sorry about the "added a commit" spam which showed up on this issue. Didn't realise github would add a separate link every time I rebased without removing the old ones.
