I've got a customer with an older 3825 in India, they had 256MB DRAM and 64MB CF. We upgraded the CF to 128 so we could support IP VOICE 12.4(24)T IOS. I found a document on CME 7.1 that shows the recommended DRAM to be 384, but it uses the word "recommended", I am unable to locate a minimum number.
Customer will have approx 65 phones connected, some custom dial plans for intra-office call routing but that's about it.
During some DM configuring the engineer claims the router crashed with a "Exceptional memory dump" error, he also claims to have called TAC and been told it was a memory leak. The customer wants us to be certain of the problem. He's reluctant on upgrading the memory if the problem is with the existing 256MB DIMM.
Is anyone familiar with the "Exceptional memory dump" error? What are the typical symptoms of a router running out of DRAM?
Thank you that's great response. However the customer is looking for a definitive answer as to why we experienced the "Exceptional Memory Dump" error. If someone can confirm that error is NOT associated with running out of memory I think I'll have enough to report to the customer with.
