We’ve 3 UM’s in cluster.
Here is the issue begins, one of the UM node was down due to heap memory issue. And we’re bringing up the UM server immediately.
Ever since, duplicate document subscription is happening. Observed that 2 times the same document is being subscribed based on our transaction audit tables.
Note: No retry mechanism configured at trigger level. And the document processing is “Serial”.
First Subscription: Document is interfacing to target successfully.
Second Subscription: Document is being subscribed by wrong subscriber eventhough the filter conditions specified correctly.
As it’s serial processing, documents are processing one by one and after couple of days it’s behaving normally. Means, the new documents are coming and processing successfully.
Can you please suggest how can we identify the root cause of this issue.
