%BGP-3-INSUFCHUNKS Error Message

If the autonomous system (AS) path length is less than 50 ASs (100 bytes), the router uses chunk memory allocation. If the AS path length is longer than 50 ASs, the router uses regular memory allocation and returns the #%BGP-3-INSUFCHUNKS: Insufficient chunk pools for aspath error message every time it encounters this situation. The router should continue working normally despite this error message.

This problem has a Cisco bug ID of CSCdr07279 ( registered customers only) . The fix for CSCdr07279 allows the router to use chunk memory allocation for an AS path of up to 125 ASs. Once the path exceeds this length, the router returns the error message only once.

The fix for CSCdr07279 was integrated into these Cisco IOS Software releases:

  • 12.0(9.6)ST

  • 12.0(10.1)S

  • 12.0(10.3)SC

  • 12.1(1.3)

  • 12.1(1.3)T

  • 12.1(1.3)E

  • 12.1(1.3)EC

  • 12.1(3)DB

  • 12.1(3)DC
