Newly upgraded firmware on a G2:
Aug 26 12:50:53.611: %SYS-4-CHUNKMALLOCFAIL: Could not allocate chunks for CEF:
Total free: 0, Total inuse: 500, Cause : Not a dynamic chunk
Followed by a traceback.
The router does not crash, so seems this is not fatal, but I don't like it.
Any ideas on a cause or a solution?
This is a known resolved bug. Typically seen when you are overloading your router with lots of packets >512bytes.
BugID is CSCsj25679 and should be fixed after 12.4(16)T although I dont think its released yet.
Open a TAC case if you need a special image released, or wait until the next version of 12.4T is released.
