Re: org.ozoneDB.ObjectNotFoundException: No such object ID:

Hi Rikard,

The reason is probably some harddisk problem. Are you using a journaling 
filesystem (e.g. reiserfs, ext3, ntfs) or a non-journaling (e.g. FAT32 or 
ext2)? 

For some options on recovering from a crash do a search on "recover" on the 
dev list. 

Another option would be to create a utility that surgically removes the entry 
for the missing object. This probably means creating a utility around 
org.ozoneDB.core.storage.wizardStore.IDTable.

Best regards,
Per
