No such errors in there on mine, but thanks for pointing me to the error log
location.

I see: 
Failed to bind to "port#" : Address already in use at
/usr/libexec/usermin/miniserv.pl line 338

I must have also missed that miniserv.pl was still running in my "ps aux"
because this morning it was listed 5 times (once for every time I tried to
restart it)  After killing those processes I was able to start usermin
again.  The last entry in the error log before the failed to bind messages
was that it was Restarting.  Looking in the miniserv.log file I saw that a
user was trying to change their theme at that same time.  I'm guessing that
is what crashed it, so I have removed the 'theme' option now.

Everything is back operational now.  Thanks for everyones assistance.
