Version update to version 3.9.6.1 or later is recommended when Brekeke SIP Server Standard Edition version 3.9.5.8 or older is integrated with RGS (Responder Gateway Server).
NOTE:
Brekeke SIP Server Advanced Edition and OEM products based on the Advanced Edition are not affected by this symptom.
Symptoms:
This issue is observed when Standard Edition of Brekeke SIP Server is integrated with Responder 5 RGS (Responder Gateway Server).
When SIP server receives SIP-REGISTER packets with inconsequence order of CSeq number, the thread will not be released. From our investigation, this issue seems to be triggered under undesirable network conditions.
As a result, if these remaining threads exhaust the assigned memory of SIP server process, the process will stop working.
For checking whether there are remaining threads:
1. Go to [Tools]->[Command] page.
2. Type “threadlist” and push [Execute] button.
3. If there is “register” thread, wait for 40 seconds or more.
4. Push [Execute] button again.
5.If the same “register” thread still exists, it is remaining thread.
