job SAP_LMDB_LDB gettig canceled in LMDM synchronization

Hi Experts,

In solman_setup we are doing LMDB synchronization and One of my job(SAP_LMDB_LDB_0000000001) is getting canceled and when i see the job log for this i got the run time error as "SYSTEM_CANCELED" and short text as "The program z-- was terminated manually"

In error analysis i am getting the message "The current program has been terminated from another mode, e.g. with transaction SM50"

I need help in analyzing what caused the short dump.

Beast Regards,

RAjesh.
