Blacklisted messages processed and delivered twice creating the duplicate data posted.

Hi All,

There is a issue we are facing about blacklisted message getting delivered twice. Need pointers to understand the reason for duplicate delivery of same message.

In SAP PI, lots of messages got stuck with delivering status, when the messaging service were restarted for resolving that, some of the delivering messages went into blacklist state. Later messages got processed successfully and delivered upon restart. After few hrs. messages shows up as removed from blacklist in the logs and went into null pointer exception error and later processed successfully & delivered again hence creating the duplicate data posted at target system.

Can any one help on the reason to process the blacklisted messages again?

Thanks,

Rajini
