On Oracle Communications Network Charging and Control (OCNCC or NCC) and Oracle Communications Convergent Charging Controller (OC3C or 3C), it is possible for the watchdog to abort and restart the slee_acs processes due to unresponsiveness.
A backtrace was not captured at the time of investigation, but from the debug, it can be seen that it last logged line was from the Number Portability (NP) code:
Further testing shows this issue occurs when a lookup is performed by the NP Destination Selection (NDST) for a number that is not provisioned in the NP number ranges.
When the same lookup is performed against a number that is provisioned, the node returns significantly faster.
