These steps are inside of dpkg, so I reassign accordingly. I do not think there is anything actionable here, and it's likely a problem with your system. > - CPU usage remains low (around 5–10%). > - Disk I/O is minimal. > - It seems APT or dpkg triggers are spending excessive time in internal > processing. Perhaps your disk is failing? If it's not blocked on CPU then it will be blocked on I/O, but not necessarily writes but ordering of syncs - you will not see them associated as writes with the process, I'm not sure if you see those at all as I/O in monitoring. It's plausible dpkg added some extra fsync calls this cycle, but I can't say for sure. -- debian developer - deb.li/jak | jak-linux.org - free software dev ubuntu core developer i speak de, en
