jBASE: Attempting to free NULL pointer at jediTran

Hi collegues,

Due to a crazy business logic, I need to charge "commissions" in Application COB STAGE ( After LD.EOD process), expected volume is at less 200,000 transactions by day thats why performance is an important topyc, currently we are using EB.ACCOUNTING ( TAX: AC ->AC & COMM: AC->PL )in order to increase processing speed, using SUB-ACCOUNTs for tax and a well programed multithread JOB but

I'm having this problems ( development area):

- First 10,000 transactions are processed with an OK time-performance (2 min - 8 agents)
- From 10,000 to 20,000 increase time for each transaction, completing in ( 10min - 8 agents)
- After 50,000 some times "jBASE: Attempting to free NULL pointer at jediTran" message is showed
- Also After 50,000 some times "jBASE: Segmentation violation. Aborting" message is showed
- After 50,000 for each 10,000 transactions it takes more than 30minutes.
- Once one of those message are showed session is terminated and all transactions already processed experiment rollback and they return to JOB.LIST.

- I'm working under R06.003 release
- AIX Server with 6 processors availables and 4 extra by demmand.
- I'm using a SUB-ACCOUNT for TAXes (VAT)
- Local control TABLES (files) are less than 1GB
- STMT.ENTRY and CATEG.ENTRY are DISTRIB.
- For this test I'm using diferent customer accounts to prevent dead-locks.

Does anyone has a suggest , comment , some past expirience like this? Do i need more HD,PROC and RAM?

Thanks a Lot.
