Description Yuri Victorovich freebsd_committer freebsd_triage 2021-06-11 20:57:04 UTC 
After unplugging and plugging webcam and plugging it back webcamd became unkillable:

> $ ps ax | grep webc
>   902  -  D<Es     0:06.95 /usr/local/sbin/webcamd -i 0 -d ugen4.3 -B -U webcamd -G webcamd
> 71873  6  S+       0:00.00 grep webc

It seems like the system needs to be rebooted.

webcamd-5.13.2.4

What does:

procstat -akk

output in this state?

Usually webcamd cannot be killed when applications are using the video devices.

It waits for all clients to exit first.

Yup, this is a bug in qTox that it doesn't close the V4L device.

Sorry for bothering you!

A thought (because I had the same misunderstanding of webcamd): the package message could be expanded, a little, to include a paragraph about things that place a hold. 

In plain English (and/or translated), a two-sentence paragraph should cover it …

pkg query %M webcamd
