Dropped calls

Unanswered Question
Jul 10th, 2009

I have a Merlin Magix PBX connected via frac PRI to a 2811 running 12.4(6)T9. The leg between the gateway and the PBX is ISDN and the leg between the GW and the PSTN is SIP. They're only using 10 channels of the PRI and are rarely, if ever all used. There are 2 PVDM2-16's in the GW. What happens intermittenly, are calls being dropped.These are calls that have already set up. My question is, please have a look at the output below and confirm for me that I have a buffer leak on the DSP resouce manager and on the interface as well. Any suggestions as to how to continue to troublshoot would be welcomed as well. Thank you.

Interface buffer pools:

Onboard DSPRM Pool buffers, 264 bytes (total 300, permanent 300):

0 in free list (0 min, 300 max allowed)

300 hits, 0 fallbacks

300 max cache size, 300 in cache

98424 hits in cache, 0 misses in cache

pp00 buffers, 576 bytes (total 1536, permanent 1536):

0 in free list (0 min, 1536 max allowed)

1536 hits, 0 fallbacks

1536 max cache size, 1024 in cache

Private particle pools:

IDS SM buffers, 240 bytes (total 128, permanent 128):

0 in free list (0 min, 128 max allowed)

128 hits, 0 fallbacks

128 max cache size, 128 in cache

0 hits in cache, 0 misses in cache

Serial0/1/0:23 buffers, 512 bytes (total 8, permanent 8):

0 in free list (0 min, 8 max allowed)

8 hits, 0 fallbacks

8 max cache size, 4 in cache

9166 hits in cache, 0 misses in cache

FastEthernet0/0 buffers, 1536 bytes (total 192, permanent 192):

0 in free list (0 min, 192 max allowed)

192 hits, 0 fallbacks

192 max cache size, 128 in cache

I have this problem too.
