[ome-users] frequent and unexpected deconnexion of clients from server

[Jacques Pécréaux]

Hi,

I experience frequent deconnexions (about every hours) when running importer / insight or matlab client. This happens while these application are exchanging data with omero server. It seems not linked to a particular dataset although it might be linked to datasets missing preview (See http://www.openmicroscopy.org/community/viewtopic.php?f=5&t=750&p=2881#p2881). Even when the client run on the same computer as the server, these deconnexions happens, ruling out network issues.

 It results in an entry into master.err log suggesting that it is maybe a bug (see below). I would be very thankful if someone could give me some suggestions to troubleshoot this bug. Please ask me any relevant information that would be useful.

Thank you!

Best regards

Jacques Pécréaux
