When poudriere jails become stuck in a loop

[Beeblebrox]

I have observed that some poudriere jails, on occasion, get stuck in a
hanging pattern. If I go to a jail that became stuck, top always shows
something like:

PID USERNAME THR PRI NICE SIZE RES STATE   C   TIME    WCPU COMMAND
91534 root 1  23    3 21840K  2376K CPU3    3   0:00   0.02% top
24713 root 1  52    3 49828K     0K wait    2   0:13   0.00% <pkg-static>
24637 root 1  23    3  9048K   148K wait    0   0:00   0.00% make
26552 root 1  52    3   190M    44K urdlck  0   0:00   0.00% dot
24652 root 1  52    3 16988K     0K wait    1   0:00   0.00% <sh>
26551 root 1  52    3 16988K     0K wait    3   0:00   0.00% <sh>

The solution I have found is to kill the process named "dot" (26552 in this
case). Poudriere then picks up from where it left off and successfully
completes the package build.

Regards.
