This is a bug (memory leak) I've meet many times, but never got an ID for.

Only workaround is to reload the router. I haven't seen it happening in recent versions.

Hello Hari,

i had the "same" problem. We updateded a CUCM form 6.1.2 to 7.1.2. So we also updated the SRST Gateways to 12.4(24)T1.

After this our 3825 Gateways with 256 MB Mem refused the command max-dn. It still worked, but only for very low numbers. (up to 23). So I opend a TAC Case and the anser was


#########################################

The system is now

telling you that there is not enough memory to add dial-peers into the

system. Note that the threshold is 80% for 256M or less, 85% for

256-512M and 90% for > 512M of processor memory. The system will not let

you add ephone-dn's (dial-peers) when it's available processor memory is

below that threshold.


Below is two relevant URL that discuss this:


How to determine the maximum number of dial-peers that can be configured

on a router

http://www.ciscotaccc.com/kaidara-advisor/voice/showcase?case=K34857008


When calculating the memory requirements for the number of dial-peers

required you can use the following:


Router>show memory summary


Head Total (b) Used (b) Free (b) Lowest (b)

Largest (b)

Processor 60AB4ED0 5550384 2082996 3467388 3464996

3454608

I/O 40000000 16777216 1937280 14839936 14839936

14838908


Total = the total amount of memory available after the system image

loads and builds its data structures.

We also saw in the following document that 512 MB of memory are recommended.
