We are using Lotus Notes LDAP custom for our authentication. Lately, around 12:30 p.m. to 1 p.m., no one can log in - it just hangs and does note error out. The query load at that time is fairly low and I have not found any processes running consistently during this time period for this duration.
Windows 2003 server, BO clustered environment, Tomcat memory 512/1024, each server has 4GB RAM
Any gurus have ideas on how to resolve or reduce?
Thank you.

Check the timeout setting in Web.xml file of your Tomcat server. You can increase the time limit.

Was there any issue with LDAP server itself? 
You can check CMS logs to verify if there was an issue with BO LDAP authentication plug-in.

During this time period, only about 25 scheduled reports are running including a simple 3 second report we use for monitoring. This report takes 5 minutes during this “slow” time period. The database it is accessing is not under load and responds well.
I will check the timeout settings but during that time period I have verified that there are zero logins which means that there is not a long list
of users trying to get in all at once.
As info, our LDAP has been problematic from the start but never an issue like this before.
Thx for your responses.

NEW INFO: When this issue occurs, the primary CMS iin the cluster is running constantly at 100% of one CPU or higher. When the issue stops occurring, the following message appears in WCA log:
An IOException occured in the application server

This is coming from someone who doesn’t do LDAP but does Windows AD, so I apologize if this doesn’t apply.
Does BOE update your authentication automatically at that specific time? I don’t see what version you’re running but I think 3.1 can be set up to update at a specific time. I’m fairly certain XIr2 can’t be scheduled.

Good thought - it does seem like some internal BO process run amok. We are XI R2 which I believe does updates after a preset number of hours of “idle time” or if you manually hit the update button in CMC>Authentication>LDAP. Our environment is busy all throughout the day. It occurs “almost” every day at about 12:34 p.m. My next test will be to disable schedules at 12 or 12:15 p.m. to see if a certain scheduled report is causing havoc with the system.
Thanks for your input, its really appreciated!
