Full log: gpionext.log

I first experienced this after about 5 mins of playing the shoot 'em up M.U.S.H.A. for Genesis, and it keeps happening every time I play it. This game has auto fire so you only need to keep a button pressed to fire. I can reproduce this even when not in the game by keeping a button pressed and randomly moving the joystick.

I might be related to #43, but I don’t seem to hit the thread cap. The error usually occurs somewhere between 2000 and 5000 threads.

Hardware: Raspberry Pi 4B 1 GB
OS: RetroPie 4.8 (fully updated)
GPIOnext: Latest git with default options

Did you try setting combo_delay to 0?

[amak79]

I did set combo_delay to 0 but the same error occurs.

How long does it usually take for you to get this error?
While you are playing, if you release the button for half a second every once in a while, does it still have the problem?

[amak79]

The error usually occurs after 5 mins.

I did a test where I would release the button every 30 seconds for half a second and the error didn't occur. I ran the test for 6 mins. The combo_delay was set to the default of 50.

Is there any way to list the current config values?

[mholgatem]

sorry, I've been away for a bit. The config variables are set as flags in the service file. You can open /lib/systemd/system/gpionext.service to see all of the currently set flags
