try 'head -50 xxxxxx.0.FDC' to view the header in the first 50 lines. 'head -200' should view the segment dumps as well.

Its likely the process is producing the same error tens of thousands of times.

If there are lots of files with similar size is probably safe to remove some of them to free up disk space.

Lacking any other automation application, you could set up a cron job to come to life every few minutes looking for fdcs. If fdcs exist, move them to some other filesystem

Having faced a similar problem in the past as Goodfellas, I have a korn shell script that can be run by cron. It moves small fdc files to a separate date/time stamped directory and deletes big fdc's (keeping a short summary). It takes a copy of the AMQERR0n.LOG files.

During a problem scenario which lasted several days until the fix was implemented, it saved our bacon by preventing the /var/mqm file system from filling up.
