Overview

The WebLogic managed server hangs, for no apparent reason, when trying to start the Service Gateway application.

Following is an example of the last several lines logged to the "/servicegateway/weblogic-domain/servers//logs/sprtManaged*.log" file before the application hangs.

####     <> <> <> <1391081260147>   Channel Weight   50
 Accept Backlog   50
 Login Timeout   5000ms
 Max Message Size  10000000

####     <> <> <> <1391081260684>   
####     <> <> <> <1391081261195>

There is no further NO activity logged by WebLogic after the last statement and the Service Gateway application is never started.

Environment

WebLogic 9/10

Root Cause

WebLogic performs a security initialization AFTER the IIOP configuration is complete. During this security initialization, WebLogic initializes LDAP. It is likely that the LDAP configuration files, located in the /servicegateway/weblogic-domain/servers//data/ldap/ldapfiles folder have become corrupt.

Resolution

Remove (or rename) the 'ldapfiles' folder and restart the managed server instance to rebuild the LDAP configuration files from scratch. This will enable WebLogic to complete the security initialization and the managed server should then continue through the normal startup process.
