DCERPCSessionError: TSCH SessionError: code: 0x80071a90 - ERROR_TRANSACTIONAL_CONFLICT

Ran into this error a couple times during a mass mimikatz run. Everything seems to be working properly despite the error. I might have been too aggressive with the thread count at 200, but thought I'd let you know.

interesting, could you give me the full command you used?

Nothing crazy:

cme -t 200 192.168.0.0/16 -u admin -p password -M mimikatz

Closing since I haven't been able to reproduce this. Let me know if it comes up in the new version
