E9.2 Orchestration stops adding records


Hi All - We are using JDE E1 apps 9.2 , Tools
1.I have created a form request using process recorder to add recurring billings lines. This is the only component in the Orchestration ( ORch B).
2.I have a UBE where it first calls an Orchestration ( Orch A) which only updates records. The B98ORCH calls Orch A in synchronous mode by passing 1 in the parameter cWaitForResponse_ER066.
3.Once Orch A completes, then Orch B is called through B98ORCH in synchronous mode. This orchestration is the one mentioned above in 1.
Both the above calls are made from the Do section of the report .
What we are noticing is , that the first couple of times when the batch application runs , Orch A and Orch B successfully executes and adds records for the first 8-10 executions.
After 8-10 calls of both Orchestrations , Orch A works without issues each time , but Orch B completes successfully but stops adding records after 8-10 executions.
Once this happens , we restatart HTML and AIS services and both Orch A and Orch B execute fine.
After 8-10 executions , we again start seeing issues with Orch B execution.
When Orch B stops executing , even though we go to Orchestrator studio and exeucte the Orchestration , it completes successfully , but does not add records. Please note that records are unique for each addition .

Any ideas on what can be done to resolve this issue ? Thanks for your time and help.
