Solution 1: Stop weblogic and delete the .Dat file from *\user_projects\domains\<base_domain>\servers\<AdminServer>\data\store\default and diagnostics
start the JVM

Solution 2:  Follow solution1 and then login to console - server - config - services - change :Synchronous Write Policy: to cache-flush. select Advanced - uncheck :Enable File Locking - save -activate changes and restart.

Error : Caused By: java.io.IOException: Error from fcntl() for file locking

Soln:
1.) Uncheck "Enable File locking " for persistent stores

==> This option is not supported while using NFS filesystem

2.) Maintain different directories for filestores of different JMS Servers and maintain a different file store for each JMS server.
