I have been having issues with this server off and on since I built it a year ago. I thought I had the problems resolved but about a month ago it became unstable again. The symptoms are random but most of the time the first sign of trouble is that the shares become inaccessible, or are very slow, or become write protected. Restarting the array will resolve these problems. However, sometimes the web UI becomes unresponsive also. I have gone as far as doing a clean install of UnRAID preserving only the shares.cfg and network.cfg. I attached the diagnostics file from when it crashed last. There are many call traces with CPU warnings. Any help would be appreciated.

Thank you, I remember reading about this before but thought it was fixed in an update so I ruled it out. However, reading through that thread It seems that on some hardware there must still be issues. After looking at how internal and external docker IP addresses work I realize that I do not need to assign separate addresses. I have changed them to bridge and will see if that solves it.
