What version of Camel and HawtDB are you using? To try to recover you would possible need to write some java code with the HawtDB API to load the corrupted file(s) and peak inside.
Down the road we recommend using camel-leveldb instead of camel-hawtdb. This uses LevelDB as the store instead which is a much more mature and widespread used store. https://code.google.com/p/leveldb/ Apache ActiveMQ 5.9 offers leveldb out of the box, and is being considered as the recommended/default store over its KahaDB store. The camel-leveldb has the same functionality as camel-hawtdb and is very similar to setup.
