问题
I'm using the Tokyo Cabinet database through the PyTyrant module, storing the data in a hash table (*.tch file). When the file reaches 65 GB in size, the following bug occurs: when a new entry is added to the database, querying the new key gives a "no such key error". However, the new key is listed when I query for a list of all keys. Furthermore, the problematic entries cannot be deleted from the table.
Can anyone explain this?
EDIT: output of 'tcrmgr inform -st -port 1978 localhost' immediately before the error:
