[Question] Is it always safe to restart osmosis when it crashes?

[doskabouter]

Currently I'm experiencing the occasional timeout on the server I fetch the changes from ( Unable to read the state from the server.)

Usage is:
osmosis --read-replication-interval workingDirectory=rri --simplify-change --write-xml-change file=changes.osc
and only if that succeeds the osm2pgsql starts

In the ideal world I would just want to restart it on failure so it can try again, but I do not know the risk of missing one update in some edgecase.
I guess it boils down to not being able to crash in any way after updating the state.txt
