DiameterControlAgent Coredumps With "ERROR: TCAP primitive received in state OpenNotFinal" (Doc ID 1206986.1)

Last updated on FEBRUARY 20, 2019

Applies to:

Oracle Communications Network Charging and Control - Version 4.3.0 to 4.4.1 [Release 4.3 to 4.4]
Information in this document applies to any platform.


Under certain conditions, the diameterControlAgent (DCA) process will core dump.  DCA is a SLEE interface on a Service Logic Controller (SLC) that talks DIAMETER protocol to the network.

As root, confirm the owner of the core:

$ file <core file>
<core file>:           ELF 32-bit MSB core file SPARC Version 1, from 'diameterControlAgent'
If the problem matches this KM, the core will have been created by DCA process.
Use gdb to open the core, and issue a "bt" to dump the information inside the core file explaining what the process was doing when it core dumped:
$ gdb /IN/service_packages/DCA/bin/diameterControlAgent <Core File>
(gdb) bt


If the "file" output included an Interim Patch suffix, identify the correct diameterControlAgent binary for gdb to match the core to.

Please refer to Note 1368101.1 for further information about taking a backtrace with GDB.

The backtrace will contain similar entries to this (note important frames highlighted in bold):
