ice model dumps history files every timestep then crashes with latest UFSWM

[jswhit]

What is wrong?

Using the latest version of the UFSWM, the ice model will produce history files every timestep, instead of every 3 hours. Denise Worthen (@DeniseWorthen) identified the problem as an unintended consquence of changes introduced in https://github.com/ufs-community/ufs-weather-model/pull/2437/files.

What should have happened?

the ice model should produce history files every 3h as requested by the GW config.

What machines are impacted?

All or N/A

What global-workflow hash are you using?

develop

Steps to reproduce

run a test using the coupled model. The ice model will dump history files every timestep, then crash after 3 hours with the message

424:
424:  (abort_ice)ABORTED:
424:  (abort_ice) error =
