drdebian Posted August 6, 2023 Share Posted August 6, 2023 Ever since I upgraded to the latest version of Unraid, I keep getting alerts from the "Fix Common Problems" plugin regarding my /var/log being almost full. Indeed it is, with the biggest files being syslog*. Looking at the syslog files more closely, 99% of their contents look something like this: Aug 6 03:14:19 ul18s009 nginx: 2023/08/06 03:14:19 [error] 3265#3265: *6574127 nchan: error publishing message (HTTP status code 500), client: unix:, server: , request: "POST /pub/notify?buffer_length=1 HTTP/1.1", host: "localhost" Aug 6 03:14:19 ul18s009 nginx: 2023/08/06 03:14:19 [error] 3265#3265: MEMSTORE:00: can't create shared message for channel /notify Aug 6 03:14:20 ul18s009 nginx: 2023/08/06 03:14:20 [crit] 3265#3265: ngx_slab_alloc() failed: no memory Aug 6 03:14:20 ul18s009 nginx: 2023/08/06 03:14:20 [error] 3265#3265: shpool alloc failed Aug 6 03:14:20 ul18s009 nginx: 2023/08/06 03:14:20 [error] 3265#3265: nchan: Out of shared memory while allocating message of size 9033.

Increase nchan_max_reserved_memory. /var/log seems to be mounted like this according to /etc/mtab: tmpfs /var/log tmpfs rw,relatime,size=131072k,mode=755,inode64 0 0 Any ideas how to further track down the issue?

drdebian Posted August 20, 2023 Author Share Posted August 20, 2023 Please, don't try to help me all at once... 😂 It's great to have to rm /var/log/* every day to keep the system running. Quote Link to comment
DarthNorse Posted September 15, 2023 Share Posted September 15, 2023 I have the same issue and from what I found most people say it's related to a client having the web-ui open (especially Android) but that's not the case for me. No clients have the UI open. Quote Link to comment
