Description of problem:
While running SAS jobs from 4 nodes with 6 jobs per node, SAS failed.

The messages from SAS are below

16SEP2018_19_52_35_refresh_mp.log..di_wrap_mg_process_unit.250.log:ERROR: A lock is not available for P_MDCPS.PARTITION_518_375.DATA.

That should correspond with file:

/sasdata/bulked/model_data_calib_ps/partition_518_375.sas7bdat

Im not sure about the file referenced in the last two entries.  My search comes up with several potential candidates ...

-bash-4.2# find /sasdata -name \*partition_130_1\*t
