In a datastage parallel job we are getting a warning
user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock
Observations : The error is coming up only for one job, and for only one set of file (large in size 400 000 to 500 000 records) in that job. Sometimes it is observing in other jobs as well, But many jobs under the same platform is working fine.
As per the above IBM doc we set the correct value for JAVA_HOME variable, But still the issue persists.
