Transaction Rollback Issue in SOA Suite

Question

Hi All,
We have been facing the transaction rollback issue very frequently and looking for a concrete solution on this. We have a Asynchronous BPEL process which calls a webservice in a loop of say 20 iteration. In the loop sometimes we face this transaction rollback issue and apparently the CatchAll block doesn't capture this.
In many blogs and oracle metalink we have seen few settings for this and made as per below :
1. JTA Transaction timeout increase : we have it 10000 sec.
2. The Data Source settings : 2.1 : XA transaction timeout check-box selected
2.2 : The Initial Capacity : 10, Maximum Capacity : 200 and Capacity Increment = 5
3. soa-infra -> EJBs -> set the transaction timeout to 1200 for many of the recommended BPELs
4. DISTRIBUTED_LOCK_TIMEOUT = 120 sec.
In short, all the recommended settings are in place. But still, we are facing this issue. Does anyone know if anything is missing in the setting ? Or any other solution to the issue?
Any help is truly appreciated.
Thanks,
Ashwini

I think, even if you change the setting you may not get rid of this problem permanently. Try to avoid call to the webservice in a loop and look for any other alternate solution like JMS (thread should not block for the response of the webservice).
