<PapaDragon> Hi all, after launching the update of 3 apps through the Yunohost admin interface yesterday evenns, I found nginx frozen this morning. I checked the logs and found these lines:
ter process /usr/sbin/nginx -g daemon on; master_process on;: ././src/store/memory/memstore.c:705: nchan_store_init_worker: Assertion `procslot_found == 1' failed.
2025/06/07 05:00:32 [alert] 1894#1894: worker process 3018809 exited on signal 6
2025/06/07 05:00:32 [alert] 1894#1894: shared memory zone "memstore" was locked by 3018809

<PapaDragon> They were repeated a few times: the /var/nging/error.log file which was empty yesterday grew up to 1,8GB. Only filled with said lines.

<PapaDragon> This looks a lot like the problem described here: https://www.claudiokuenzler.com/blog/1022/debian-buster-nginx-1.14-nchan-error-logs-memstore-assertion-failed

<PapaDragon> I'd have only one question: would it be safe to simply remove the nchan module or do I have to consider that it was probably called by the system at some point and therefore is somehow manadatory?
