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.
