what causes Thread already associated with Transaction error Guvnor 5.5.0.Final ?

[thomas.setiabudi]

Hi,

I use KnowledgeAgent to get process definition from guvnor for my JBPM project.

However, randomly the Guvnor5.5.0.Final will run into error

Attached the server.log

Anyone know what is the cause or the solution for this?

Hi Thomas,

Did u find the root cause of this issue and the solution for this issue. There is a issue logged in Jboss JIRA for SEAM TRANSACTION, but there is no solution I can find for this issue.

I have a web application which accesses Guvnor. We have processes and forms in Guvnor repository in a package. Guvnor is configured with JackRabbit and Oracle 11. Our web application accesses the process definitions and forms from guvnor. The issue gets fixed on restart of server. But, once this issue occurs, application can't access any asset or process definition from Guvnor using rest APIs. Even the Guvnor web-interface starts giving error. Only 4 users are using the application and getting this transaction association error.

Following is the environment for the jboss instance where guvnor is configured.

1. drools-guvnor-5.5.0-Final
2. JBOSS ASS 7.1.0
3. Oracle 11

hi community,

any idea about this error?

This error seems to happen at random time, but any fix for this?
