CMT Import on cloudnative environment is not happening as expected Dat files & Log file not matching

Hi,
We are trying to migrate accounts in cloud native environment but we are facing a peculiar issue where dat files are created by CMT but log files are not created or dat files created but log files with 0 size and some times data is not loaded from dat files.

Also in cmt.pinlog we are seeing below error:
