Defect HC-13229

Parallel NRTs crashing Nifi


Customer case Applies to Corrected in
CS0268148 V9.1.6.0

Observed behavior

When multiple NRT indexing operations are run at the same time, NiFi processing can end abruptly. This has been known to happen during Rule Based Sales Category processing when there are several of these categories in use.

Expected behavior

Concurrent (parallel) NRT indexing operations should not have a negative impact on system stability.


Improper handling of database connection pooling caused multiple concurrent operations to compete for resources, leading to NiFi processing to end. The database connection pooling was fixed to avoid this situation.
