Grouper Users - Open Discussion List

[Jared Hoffman <>]

When we have several grouper loader jobs running we occasionally get timed out errors for some loader jobs. We still use the sources.xml config (plan on patching to current in October break maintenance window). 

The "timeout used" in the error is -1, so I'm wondering if that is an unlimited timeout. Or if there is a timeout setting we haven't found. We tried adding "ldap.personLdap.timeout = 5000" to grouper-loader.properties, but I think that needs to be closer to the sources.xml AD/LDAP config.  

I read through this thread from the list but we don't have an ldap.properties config. We are using the sources.xml config. Do we need to get all the current patches to be able to set the timeout properly? I could schedule a special maintenance to patch if it would be easier to manage.
