Zefa Guan updated JBTM-2746:
----------------------------
    Description: 
when setup txbridge under Tomcat8 out of JBoss, I am facing performance issue as below scenario;
1) running 3 tomcat instances
2) A call B via WS
3) B call C via WS
4) when 100 - 200 GET query from " http://localhost:8081/user?action=add " via Service A, all 3 tomcat got stuck for a while then raise exception with attached logs
---------------------------------------------
the reason may cause by race condition/socket timeout/exceed limits, will need to reproduce and research more
at the beginning I thought it was caused by DB resource locking failed but after I commented out all DB access, the problem still there
put all my code to https://github.com/JonkeyGuan/txbridgeInTomcat8 for reproducing and reference

{code}
     servlet client - localhost:8081/user?action=add
