Description (partial)
Symptom: The SPP process may crash repeatedly with invalid buffer count. Invalid buffer count PPORT = 9, LPORT = 4, PCOUNT = 87 RP/0/RSP0/CPU0:Oct 2 21:47:07.492 : dumper[60]: %OS-DUMPER-4-SIGSEGV : Thread 1 received SIGSEGV - Segmentation Fault RP/0/RSP0/CPU0:Oct 2 21:47:07.492 : dumper[60]: %OS-DUMPER-4-SIGSEGV_INFO : Accessed BadAddr 0x280 at PC 0x280. Signal code 1 - SEGV_MAPPER. Address not mapped. Since SPP is a mandatory process then a kernel crash will be seen after the SPP process cannot be restarted. Conditions: This has been seen on a ASR 9001 running 5.1.2 or 5.1.3
