When some of our Hybris servers are restarted, we are getting the below error in the logs:

Same situation here, any clues?

[Former Member]

any solution??

[former_member519693]

Try to republish all and see if it fix

[Former Member]

That will be a manual effort every time.

What we discovered is that there are some characters such as ' and %, that, if placed in a rule, it will cause the entire drools module to not start. The solution to this was to remove the rules with the "bad" characters in them and then restart the drools module and it appeared to solve the issue.
