we had this problem when there was more then 100 users on one hdlc card,
as you know the limit is 128 (not 192).
ascend told us that for best performance we should use only 60 max. 90.
so we add hdlc cards and limit each for 96 users with call-route profile.
you must look when it happens how many channels in use at the hdlc card.
in addition get into the hdlc card and write pools -v if the available
memory
is below 600k there will be problems, so you must reset the hdlc card once
in
a while to free some memory.
