Subject Ignite transactions stuck between PREPARED and COMMITTING
Date Thu, 02 Apr 2020 17:34:08 GMT
Hello experts,

Cluster details: Running Ignite 2.4.0 with 3 servers and 4 clients. 

Observed transaction timeouts after a server node restarted. Upon further
investigation, it was due to PME failures and also saw that there were some
long running transactions on a cache for the same key for more than 9 days
(duration=840832760ms). 2 client nodes had created the write (delete the
key-value) transaction at around the same time with timeout set to 50ms.

One of the transaction was stuck in state=PREPARED and the other in
state=COMMITTING. Is there any known issue in 2.4.0 which causes this
deadlock? Why did Ignite not honor the timeout value of 50ms and bail out?
