Oversize msg from hobbit procs test

I'm getting this on my hobbit server:

Latest errormessages: Oversize status msg from 192.168.224.150 for hnae.sec.mhc.net:procs truncated (n=290936, limit=262144)

This seems to be because the hobbit client returns the entire output of "ps aux" or something similar. Is there a good way to limit the number of lines being sent? Our servers have a LOT of running processes.
