Newsgroups: comp.dcom.sys.ciscoThis is some stuff I found dealing with the command: -----------------
static ulong process_max_time; /* Max allowed tick count for any process */ sets the max voluntary duration for a process. i believe this is used
to set how long a process may run. i have seen the command parsed into the
config when you load recent (11.3(9.x)T IPSec) code.
------------------
It somewhat limits the amount of time a given process can hold the CPU
for (in milliseconds). It's a knob that I think has always been
there, but recently became un-hidden because if processes run for too
long and we're process-switching voice traffic for some reason, voice
quality suffers across the box. Unless you're process-switching voice, you don't need to touch it. If
you are running voice, dorking with it (down to 50-100ms or so) may
improve voice quality across the box
------------------------------
we limit the amount of time a process level activity can hold onto
CPU in case we were process switching voice traffic. otherwise voice
quality is going to suffer.
