Merging a Branch ruleset hangs DEV system

Hello there,

Our entire DEV system hangs while trying to merge a Branch Ruleset with just 5 rules. Even after 30 mins, I see the Pega 7spinning wheel and no developers are able to work when the system hangs.

Every time we have to restart the Tomcat VM when this happens, and see that just 1 or 2 rules merged and rest not merged.

This is happening consistently with the following exception in the log files:

Error Message Unable to synchronize on requestor H621F8137C48F7191B6FCC7B2A2261D5F

within 120 seconds: (thisThread = http-bio-8080-exec-604) (originally locked by = http-bio-8080-exec-609) (finally locked by = http-bio-

Pega 7.1.4 (CPMFS 7.12)

Tomcat 7

MS SQL Server 2012

I had multiple browser sessions open while merging, does the exception indicate something to do with multiple sessions for my account?

Please advise if you have faced similar issues while merging Branch rulesets, and possible fix.
