Mason_handler taking 100% of CPU

We are running RT 3.4.2 and we are having major problems with the
mason_handler process taking all of the CPU on the machine and forcing
us to restart the webserver. After we restart, things work fine for
about 15 minutes and then it goes back to sucking all of the CPU. We are
not sure how to debug this problem or to see what mason_handler is doing.

Any help is greatly appreciated.
