Update

We have discovered that WEKA is not releasing a lock file because it believes another process is still using it.

WEKA are investigating the connection between the initial process that acquires the lock and the process that terminates but leaves the lock file hanging.

We are actively working with the WEKA team to trace the involved processes.
