Disktemp.py error during large/long writes to disk

I was wondering if anyone else gets this error?

File “/usr/local/lib/collectd_pyplugins/disktemp.py”, line 62, in read
with Client() as c:
File “/usr/local/lib/python3.8/site-packages/middlewared/client/client.py”, line 286, in init
File “/usr/local/lib/python3.8/site-packages/middlewared/client/client.py”, line 124, in connect
rv = super(WSClient, self).connect()
File “/usr/local/lib/python3.8/site-packages/ws4py/client/init.py”, line 223, in connect
bytes = self.sock.recv(128)

I started receiving it when I moved up to TrueNAS 13 (I think I was on 11 previously) and when I start really using the drives and likely they are getting warm. Currently running TrueNAS-13.0-U6.1.

I found this old post in old forum. I actually have SNMP disabled on the server.

Any ideas?

Likely to be a bug… that somehow your system has triggered.
There have been some other reports.

TrueNAS 13.3 BETA is coming out soon… it may have a fix. Would be keen to know if it does not.

Another strange behavior. While its “locked up”, I can’t access my other 2 TrueNAS systems that are on the same network. (running same versions)
