Further info:

Here are some of the vt.middleware settings:

# pooling options
edu.vt.middleware.ldap.pool.minPoolSize = 2
edu.vt.middleware.ldap.pool.maxPoolSize = 5

# timeouts
# 0 equals block indefinitely
edu.vt.middleware.ldap.timeLimit=0
# number of ms to wait
edu.vt.middleware.ldap.timeout=500

# retries
edu.vt.middleware.ldap.operationRetry=5
# number of ms before retrying
edu.vt.middleware.ldap.operationRetryWait=5


And I’ve taken the load balancer out of the mix by going directly to one of the LDAP servers. And fortunately I’m not seeing this in production. It should be as simple as comparing and contrasting the two systems, but so far I’m not seeing it as they are configured very much the same. I have two hairs left. :)

I’m seeing an odd issue when our test system restarts after a session timeout. It happens with both the new UI and WS. After the app session timeout, it usually takes 3 “start again” clicks or 3 hits against the api before all is good again. It appears that the error relates to our LDAP connection, but that may be a red herring. Below is an example log entry. Does anything pop out to anyone what might be happening? We are using tomcat6, java 7, and version 2.2.1 of grouper on RHEL
