Lsof: no pwd entry for UID

While troubleshooting another issue I found that lsof was outputting a ton of lines indicating:

lsof: no pwd entry for UID 911

Checking to see which PIDs were started by 911 I found a few of them (all rock-ons it appears):

Not sure what I am dealing with yet and if it’s actually a problem (looks like it… but I’m 2 days into using Rockstor so I cannot say for certain…).

@sfinney

Those processes are running as the uid specified in the rockon installation (This is an option you fill in manually)

It seems likely that you’ve entered an invalid uid into the installation window (or a uid for a user that has subsequently been removed)
You may be able to correct this by creating a new user with this uid in System -> Users -> Add user
