I have seen this sort of panic twice now on 2 separate machines when
restarting telegraf the odd time. Does this look familiar to anyone ?
On a 14.2R this popped up
kernel: freeing uidinfo: uid = 884, sbsize = 115664
and then a few min later

and just now in a VM a similar sort of pattern. uid 884 is telegraf and
I was mucking about with the configuration.
And on a RELENG_14 box (kernel from Jan 31st)
