While running poudriere on #FreeBSD 15.0

[00:13:44] [64] [00:00:00] Builder starting
jail: prison limit exceeded
jail: prison limit exceeded
[00:13:48] [64] [00:00:04] Builder started

Just how many jails am I running?

[12:54 pkg01 dvl ~] % jls | wc -l
201

Well, that's not so many. I have 72 CPUs.

[12:55 pkg01 dvl ~] % sysctl kern.smp.cpus
kern.smp.cpus: 72

And the load seems reasonable:

[12:56 pkg01 dvl ~] % w | head -1
12:56PM up 6 days, 1:14, 6 users, load averages: 112.66, 121.46, 116.97

There are three poudriere builds right now:

* overnight build
* devel/viewvc-devel with python 3.12
* sysutils/nut with python314

pkg01 is, itself, a jail. Here's that limit:

[12:59 r730-01 dvl /etc/jail.conf.d] % grep max pkg01.conf
children.max=200;

I'll boost that to 250, just because sometimes demand grows....
