Brekeke SIP Server Standard Edition may not release thread resources when it is integrated with Ametek’s (Rauland-Borg) Responder 5.

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.

 

 

Affected Brekeke products and versions:
