WebtopNaming - can not find server name for server ID

Question

We have a LB, and web servers in front of OpenSSO app servers in our environment.
OpenSSO debug log CoreSystem fills up with lot of errors like these:
ERROR: WebtopNaming.getServerFromID() can not find server name for server ID : 07
com.iplanet.services.naming.ServerEntryNotFoundException: Cannot find server.
Sometimes, it even complains about a server id (07 in the following trace) which doesn't even exist in the Site Id Table.
There are no changes in the configuration. DNS is properly configured and all the servers and their connectivity are available. CoreSystem throws these errors even after a restart of opensso app servers.
Any ideas about the root cause?

Answer 1

Thank You for the response.
Here is my site configuration in OpenSSO:
There are 4 servers in the two opensso hosts (2 secure, 2 non secure)
Servers:
http://host4.company.com:8080/openSSO
http://host5.company.com:8080/openSSO
https://host4.company.com:8443/openSSO
https://host5.company.com:8443/openSSO
Only one site with secure URLs is configured
Sites:
site1
Primary URL: https://opensso-qa.company.com:443/openSSO
Assigned Servers:
https://host4.company.com:8443/openSSO
https://host5.company.com:8443/openSSO
From the CoreSystem log, Server ID definitions are:
https://host4.company.com:8443/openSSO=01
https://host5.company.com:8443/openSSO=02
https://opensso-qa.company.com:443/openSSO=03
http://host4.company.com:8080/openSSO=04
http://host5.company.com:8080/openSSO=05
Sometimes it throws an exception with existing server IDs. But sometimes it also complains about non existing server IDs.
