Unix error code 24. Apr 12, 2018 8:40:51 AM java.util.prefs.FileSystemPreferences syncWorld WARNING: Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock. As you can see here, i am running my 15,000 virtual users run in non-gui mode...e verything looks to be fine until i hit this error "java.util.prefs.FileSystemPreferences checkLockFile0ErrorCode" The error rate jumps from 0% to 80% from that time. There seem to be something wrong. Where can i start looking and any settings that i can change to get this resolved ? We are at a critical stage of our testing and i really need a resolution for this issue. Thanks for the all the help. -- You are receiving this mail because: You are the assignee for the bug.
