May 13, 20251 yr Lately my unraid server has been crashing frequently, I have done the following to try to resolve it, Can anyone give me any suggestions? This is the error I saw locally from a monitor connected to the machine: Unraid login: php-fpm[9655]: [WARNING] [pool www] child 3927911 exited on signal 9 (SIGKILL) after 64.252728 seconds from sta... /usr/local/sbin/monitor_nchan: line 59: 3931614 Segmentation fault logger -t $nchan_id -- "Stop running nchan processes" /usr/local/sbin/monitor_nchan: line 59: 93813 Segmentation fault logger -t $nchan_id -- "Stop running nchan processes" /usr/local/sbin/monitor_nchan: line 59: 202725 Segmentation fault logger -t $nchan_id -- "Stop running nchan processes" I have enabled the syslog server, but there are no errors showing in there. I notice the crashing when I attempt to log into the web interface and it either freezes or stops loading a new page. At that point SSH no longer works, and you can't login locally either, BUT docker continues to run and I can still reach the web interface of several docker containers. the only way to get it working again is to pull the power and completely restart the machine. I'm unable to run "diagnostics" because once the crash happens I can't log in to the server to create the diagnostics, and after I restart, it doesn't have anything saved from before the restart. I ran MEMTEST 1 pass with 0 errors. I updated to the latest version 7.1.2 The crashes seem to happen when I'm attempting to load a new page in the web interface too fast.

Also, get us diagnostics while things are working well. It will still tell us a lot about your configuration and hardware.

May 13, 20251 yr Author Slightly unrelated, but I tried using the Unraid USB creator to flash a new flash drive with my usb backup.zip and it looks like it isn't copying the config folder? When I boot to the new usb drive, it acts as if its a completely new OS install.

Is there something I can do to make sure I don't have anything doing excessive read/writes to the flash drive that might kill this one in the future? I currently have 20k reads and 10k writes after 19hours of uptime. Edited May 14, 20251 yr by Mr_Assister

May 14, 20251 yr Author My apologies, I forgot about this yesterday when troubleshooting the flash drive.

May 27, 20251 yr Author Solution Just an FYI: I swapped out for a new flash drive and haven't had any crashing for 2 weeks.
