I've noticed that when that computer has been running a while (it could be after just a few days, or a week or more), dosemu2 starts failing when it runs, and it gives this error: dosemu.bin: ./build/../src/base/misc/ioctl.c:306: void ioselect_init(void): Assertion `syncpipe[0] < MAX_FD' failed.ERROR: cpu exception in dosemu code outside of VM86()!Aborted (Signal sent by tkill() 441761 1000)ERROR: Please install gdb, update dosemu from git, compile it with debuginfo and make a bug report with the content of ~/.dosemu/boot.log athttps://github.com/dosemu2/dosemu2/issuesPlease provide any additional info you can, like the test-cases,URLs and all the rest that fits. When it happened most recently, I was using dosemu2 2.0~pre9-8412-b15ad8fad+202312111916~ubuntu22.04.1. I'm wondering what might cause this error? Eric
