Hi,
I'am not sure this is the correct channel (We have premium support) – but I'am sure you will point this issue to appropriate contact… Approx. Month ago we updated/upgraded sogo (apt update && apt upgrade) – we use »https://packages.sogo.nu/release/5/ubuntu/ noble noble«. Today was the 3'rd time in a month-period sogo stopped working (Works 6-10 days normally then stops) so i know it is not exidental and it has to do with upgrade (Since we did nothing else on this server – it is sogo dedicated – imap, sieve lives on another server). Our system (We monitor memory usage and is not the problem): Ubuntu 24.04.3 LTS Sogo 5.12.4-1, sogo-activesync 5.12.4-1 RAM: 240gB Workers: 465 SxVMemLimit = 450; A lot of errors in sogo.log: Feb 19 06:54:19 sogod [548762]: <0x0x5b3cfabd6580[WOWatchDog]> Terminating with SIGINT or SIGTERM Feb 19 06:54:19 sogod [548762]: <0x0x5b3cfacb6130[WOWatchDogChild]> sending terminate signal to pid 596017 Feb 19 06:54:19 sogod [548762]: <0x0x5b3cfacb68d0[WOWatchDogChild]> sending terminate signal to pid 582798 Feb 19 06:54:19 sogod [548762]: <0x0x5b3cfaa24830[WOWatchDogChild]> sending terminate signal to pid 596290 Feb 19 06:54:19 sogod [548762]: <0x0x5b3cfad3e890[WOWatchDogChild]> sending terminate signal to pid 596018 … Feb 19 06:54:20 sogod [548762]: <0x0x5b3cfabef5a0[WOWatchDogChild]> sending terminate signal to pid 548772 Feb 19 06:54:20 sogod [548762]: <0x0x5b3cfabf0250[WOWatchDogChild]> sending terminate signal to pid 589380 Feb 19 06:54:20 sogod [548762]: <0x0x5b3cfabf54b0[WOWatchDogChild]> sending terminate signal to pid 590175 Feb 19 06:54:20 sogod [548762]: <0x0x5b3cfabf5e70[WOWatchDogChild]> sending terminate signal to pid 581533 2026-02-19 06:54:20.005 sogod[548762:596490] Forcing termination of EAS loop.
