We've increased the following so far with out disaster:

MAX_MCLASS from 16 to 64 allowing increasing the number of queues.

MMAX_JOB from 4096 to 32768 and MAX_MJOB_TRACE from 4096 to 32768.  
This allows the number of jobs in the system to be increased.


MAX_MRES from 1024 to 8192. This limit was reached when we had more  
than 1024 job slots.
