Too Many Open Files. What's the cause?

Getting the following message in live log. Appears after switching HDMI inputs with the receiver on or in standby after a short period.
Never saw that before. Osmio4K, ViX 6.6, MOHAMED_OS 2.24.07-11807-802.
Too many open files? How do I find them and reduce the number of or simply fix the issue?
A restart oscam in the oscam webif doesn't fix it. Only a deep standby and restart will.

lb_mode was 1. Changed to 2. Let's see what happens now.

Edit:
Looks better now. Only thing now is when changing HDMI inputs for a bit. Returning back to the box, channel is frozen. A channel change and back seems to fix it. I can live with that. Just don't remember it happening before. Wondering what happens when recording or watching another input and a scheduled event occurs. Will see.
