New issue 100 by be.lietaus: Diameter response lost as activity starts in
non suspended mode
http://code.google.com/p/jain-slee/issues/detail?id=100
Issue: Creating Diameter activity starts them in non suspended mode.
Problem: This can cause a loss of first Diameter response if the response
comes earlier than the SBB entity attachment to Diameter ACI transaction
commits.
Reproduce scenario (all must be done in a single event e.g.
onServiceStarted):
1. Create Diameter activity by calling:
net.java.slee.resource.diameter.cca.CreditControlProvider.createClientSession()
2. Attach SBB entity to its ACI
3. Create and send Diameter request (e.g. CCR) to diameter server
4. Wait more time than required for Diameter answer (CCA) to come (could do
some long processing work here or Thread.sleep for 10 seconds or more) -
i.e. the answer must come earlier than onServiceStarted event can be
finished.
Result:
The response event (CCA) is missed because SBB entity is only going to be
attached to ACI after the onServiceStarted finishes (transaction commits).
Since the diameter activity is started in non-suspended mode, the CCA
response event is lost.
The issue exists from 1.4.0 FINAL version in Diameter CCA RA and appeared
after this fix:
http://code.google.com/p/mobicents/issues/detail?id=3114
Other Diameter based RAs (Cca, Ro, Rf, Sh, ...) might have the same problem.
Attaching an example patch to fix this issue for Diameter CCA RA below.
