I found that occasionally jackhammer fails with an error like

2026-04-29 18:51:42.213	
Error in setup_server script! Exited with return code 1

Looking for mcs file...                           Mcs file found: MicrowaveMuxBpEthGen2-0x02040000-20260414104316-ruckman-33885cfb.mcs

A bit of debugging on smurf-so7-lat revealed that this doesn't happen on a soft hammer (restarting the streamer without power cycling the slot), and that adding a delay between power cycling and querying the crate ID seems to resolve the issue.

Probably needs a bit more testing to confirm this is the mechanism for the failure.
