Glauber noticed long delays between hitting a key, and seeing data come up on the virtual console. Looking into this, I found that the wake_parent routine that reads from all devices was actually starving out the parent after sending the parent a signal to wake up. The thing is, the child which takes the console input is recognized by the scheduler as an interactive process. The parent,

plain text document attachment (lguest64-loader.patch) I noticed that the lguest loader code for i386 was in Documentation/lguest. Well, that's fine (I guess) but it can't just be for i386. So I made a separate directory to put the loader code in. So now we have: Documentation/lguest/i386/... for the lguest i386 loader. and Documentation/lguest/x86_64/... for the lguest x86_64

Thanks for the interesting puzzle to crunch! Looking at these few bread-crumbs, I wager an educated guess that this loops in `sendcmd()` (where CLI child processes talk to a daemonized copy which tracks the timers for events), around here: https://github.com/networkupstools/nut/blob/v2.8.0/clients/upssched.c#L583-L626 for the daemon and here for the child:

The previous code: fcntl (fd, F_SETFL, O_NONBLOCK) was technically incorrect, because it would have reset any other flags on the file descriptor.

Exit with 3 as return value when fusermount fails, because the specified mount point is not considered mounted for the user. This is in line with what the guestunmount documentation says. Adapt the test-guestunmount-fd test to the updated return value. Thanks to: Maxim Perevedentsev. --- fuse/guestunmount.c | 2 +- fuse/test-guestunmount-fd.c | 8 ++++---- 2 files changed, 5

Since the first patch: - The program is now called 'guestunmount'. - I tested the --fd option and it appears to work. - You can now control retries / quiet. - Revised man pages. - Includes tests. I'm just running through the automated tests now. Rich.

After launching the command several times, with debug (posted by new code in a new branch for the investigation) confirming that the same daemon handles operations from the new client instances, its strace now has numerous FDs to report after select() - so I guess it is a problem of detecting an exit of the counterpart. 0.000000 [D2] parse_at: is 'heartbeat at localhost' in AT

Hi, Great work Jim! I?m glad you could reproduce the problem and found a potential culprit. Just for my own interest I restored upsshed from my backups (version 2.7.4-13) and it seems to running ok, so no big runtime changes regarding that with Debian 12. It is not hogging CPU. From the daemon log the heartbeat seems to be working ok. Only difference between the old logs (pre Debian 12 update)

FWIW, I wonder if this is a fallout of PR #1274 : https://github.com/networkupstools/nut/pull/1274/files and specifically https://github.com/networkupstools/nut/commit/550064930e369fb3a322c3b28ffff8b4acf53532 which added a `sock_read()` loop continuation effectively if `pconf_char()` returned 0. Just grasping at straws here (since it is a change a couple of months before the release was cut),
