Hello there,
Frankly, I am quite puzzled. I have synapse (matrix) server installed
in
a jail. When I restart the jail, the process not only survives the
restart, but start itself once again as well.
Before `service jail restart matrix`
```
So, basically I have two questions so far:
1. Just out of curiosity, how is that possible - a residing in the jail
process survives the jail restart. Is it common things and I missed
something about jails? Or it is just for python (maybe another
interpreter)?
2. How to solve this? Meaning force the jail behave as it should,
meaning the processes in the jail should be restarted as far as the
jail
is restarted.
It looks like you've answered #2 yourself, but this is still something
that shouldn't be happening. The only time stopping a jail should
result in the jail still existing with old processes is if those
processes end up completely unkillable (which generally points to a
different problem).
I wonder if leaving the rc system out of entirely, and just restarting
via jail(8) would change anything. Does a "jail -rc jailname" give any
different results?
I have posted more details in another thread here on the FreeBSD.org
forum:

It turns out, that I made a mistake in /etc/jail.conf - in the new
jail section didn't wrap the IP in quotes, it looked like this:
Code:
$ip= 8 ;
This fix worries me, because that doesn't look like a line the requires
quoting (unless you want the spaces to be part of the value). Also, the
fact that the unquoted value caused the symptoms it did without any
error messages is wrong even if quoting the value fixes it.
I'd like to see the entire jail.conf, and see if I can reproduce and
pinpoint this problem.
