Management Console Crashes with Java Runtim Error

Hi,

We have been getting this error randomly where Managment Console crashes after some time when trying to refresh the batch job status page or even selecting a repository. A quick SCN search did not return any relevant threads for this error. Just wondering if anyone has come across or would know why this error would start appearing all of a sudden?

Thanks,

An application internal error occured: while trying to invoke the method com.acta.admin.AwAdminUsers.get(java.lang.String) of a null object returned from com.acta.admin.AwAdministrator.getUsers()

1. java.lang.NullPointerException: while trying to invoke the method com.acta.admin.AwAdminUsers.get(java.lang.String) of a null object returned from com.acta.admin.AwAdministrator.getUsers()
