Hi all, my bot suddenly does not work and when I check the error log, it writes: 2024-09-05 00:39:13,288: OSError: write error.

I also checked the server log and it writes: 2024-09-05 06:01:47 ...brutally killing workers... 2024-09-05 06:01:47 Thu Sep 5 06:01:47 2024 - received message 0 from emperor 2024-09-05 06:01:59 uwsgi_master_manage_emperor()/read(): Bad file descriptor [core/emperor.c line 2442] 2024-09-05 06:01:59 lost connection with my emperor !!! 2024-09-05 06:01:59 VACUUM: unix socket /var/sockets/yishao1.pythonanywhere.com/socket removed.

may I know what is happening?

Thanks for letting us know! It looks like after our system maintenance this morning, some SQLite databases were stuck in a "locked" state where processes would hang when they tried to access them. We just restarted the file locking service on the file server associated with your account, and your site is up and running now, so we think that was probably the cause of the issues you were seeing.
