Subject Derby on NAS = corruption ?
Date Wed, 18 Jul 2012 08:56:59 GMT

I work in a french company which provides secure online file management 
services (SaaS solutions).

In one of our applications (backup software), in case of a large file, 
we cut it into blocks and we use a Derby db in order to maintain the 
block indexes. These Derby dbs (version are stored on a NAS 
(cluster Isilon NL series) shared between webservers. The derby db is 
directly  acceded on NAS and it is thread safe.
Everyday, we are observing many Derby db corruptions (Unknown page 
format at page Page(524,Container(0, 1024))) and these dbs are no longer 

I join the derby log file corresponding to the last night on 1 webserver.
Thanks in advance for your help.

Best regards,
Miguel Santiago
