WebLogic Server startup Hangs at IIOP subsystem enabled
If your WebLogic Server startup Hangs at IIOP subsystem enabled then this post will help you demonstrate the solution to this issue.
Below are last few logs of stack trace.
<Info> <Socket> <BEA-000436> <Allocating 129 reader threads.>
<Info> <Socket> <BEA-000446> <Native IO Enabled.>
<Info> <IIOP> <BEA-002014> <IIOP subsystem enabled.>
If there is NO activity after the IIOP subsystem enabled then there is some problem with the Initialization of some Security configuration(s). Usually after enabling IIOP subsystem weblogic server initiates “security” data located under (“\servers\<server_name>\data” folder) might have been corrupted. So you will have to rename the ldap folder located under (“\servers\<server_name>\data”) and start the Weblogic Server.
