Mirrormanager's crawler not running

[Matt_Domsch at Dell.com]

Ugh, that's twice recently then.  I need to revisit that pid handling code in MM.  It looks like it does open()/write()/close(), so not a lot of room for error, but who knows...

Hi, this was due to a stuck lockfile - I've restarted the crawler now.

This happened earlier today with update-master-directory-list too, which caused people to get hash mismatches with yum.  What happened was that /var/run/mirrormanager/crawler.pid and /var/run/mirrormanager/umdl.pid were empty, which prevented both of these processes from running since sometime on the 13th.

I'm not sure how this condition occurs - maybe the process updating the pidfile somehow got killed before it wrote the pid in?  It is strange to see the exact same problem with two different jobs though.

Thanks,
Ricky
