I have several presentations (2 specifically) running on Raspberry PIs that both “hang” after about 15 minutes or so. Both are configured to run continuously, with 2-3 second delays between slide transitions.
Currently running on Raspberry PI, Debian 11.2 with libreoffice 7.0.4-4+rpi1+deb11u1.
In trying to figure out what was hanging, I used strace to find out what the program is doing. In all cases when it hangs, it is stopping on calls to _newselect, generally similar to the following:
_newselect(9, [6 8], NULL, [8], {tv_sec=1254786, tv_usec=202252}
The timeout is like 14 DAYS, where I would expect it to be 2-3 seconds for most slides. The full presentation is only a few minutes, and it always seems to stop at about 15 minutes or so.
This seems to happen with multiple presentations.
Any thoughts, or additional information I can provide?
