One of the participating databases or systems might be experiencing heavy load, deadlocks, or holds locks on required resources, preventing its part of the distributed transaction from committing.
Participant System Failure
A sudden outage or crash of one of the systems involved in the distributed transaction during the commit phase can lead to a failure to acknowledge or complete its part of the 2PC.
Transaction Timeout Configuration
Mismatched or too-short transaction timeout settings across the various systems participating in the distributed transaction can cause the commit to fail if any step takes longer than expected.
