Subject: [MTT users] mtt fails, error: identical key already exists
From: Muhammad Wahaj Sethi (sethi_at_[hidden])

    I am running mtt daily using a cron job. After every successful execution, next mtt execution fails with the following error message.

*** ERROR: An identical key already exists in memory when MTT tried to read the file /lustre/ws1/ws/hpcmtt-mtt-0/mtt-scratch/sources/mpi_sources-ompi-nightly-trunk.1.9a1r30043.dump (key=1.9a1r30042). This should not happen. It likely indicates that multiple MTT clients are incorrectly operating in the same scratch tree. at /zhome/academic/HLRS/hlrs/hpcmtt/mtt-trunk/lib/MTT/ line 131.

I have checked mtt successful run log file and was not able to notice something unusual.

Kindly, let me know if addition info is required.

Any help will be greatly appreciated.
