MaxMessageSize in rsyslog is too small for some debugging output in the stash-cache image #112

I was doing some debugging today and saw the message:

rsyslogd: imfile error: message received is larger than max msg size; message will be split and processed as another message [v8.2102.0-117.el9]

in the output (docker logs -f stashcache). It might be a good idea to increase the max msg size in rsyslogd in the stash-cache image. I think that it's just a matter of adding something like:

    $MaxMessageSize 64k

to the rsyslogd.conf file.

Particularly, if you set the pss client debugging up to level 4, you'll notice the current rsyslog regexp doesn't recognize the xrootd client-based lines as a valid logging line. That causes all the logging lines from the client to be concatenated into a single, large line (or so rsyslog believes) and triggering the error message reported by Ron.
