Thank you for your help Thomas

I don't encounter any problems with my home network (my NAS has NFS) but 
the errors appear on our network at work. It is *Novell Netware* but I 
don't know much more (I should have more information soon).

I tried different values for RECONNECT_CHECK_DELAY. It changes behaviour 
but the random failures are still there. High values also slow the 
execution (but I understand there's no silver bullet).

Yes, I execute the unit tests from Eclipse (it's more practical). I let the 
assistant configure the project automatically. The tools need dependencies 
that are missing but the main and test sources seem OK. My Eclipse project 
must lack some properties in order to find the message texts but the 
engine's behavior should be OK shouldn't it ?

Please, could you give a little more information on how the SERIALIZED 
file_lock works. Exclusive locks FILE, SOCKET and FS are well explained but 
the magic of the SERIALIZED lock is more obscure.
By the way, Isn't the last part of 
http://www.h2database.com/html/advanced.html?highlight=serialized&search=SERIALIZED#file_locking_serialized
 
obsolete since you fixed it with build 160 ? And shouldn't issue 311 be 
closed ? Maybe I'm missing something...

We're very interested in using the SERIALIZED file_lock because it allows 
our end-user to put the database on a NAS for instance without the need to 
install and manage a H2 server. The database may also be installed locally 
but accessed by more than one application. So, we retained the SERIALIZED 
mode by default and advice our users to install a server when there really 
is concurrency or when performance is an issue. However, several of our 
end-users reported corrupted database and we think it's linked to the 
SERIALIZED mode since we can reproduce some errors by stressing the 
database in this configuration and not when the database is behind a server.

That's why it matters for us and we are ready to help stabilize the 
SERIALIZED mode. Thanks again for your help.
