Hello,

we have a problem that is periodically happening on customers side every 1 or 2 weeks. We are using Jaybird 2.1.3 with Firebird 2.1.3 Classic (64 bit) on a Windows Server 2008 R2 machine.

As described in subject, java threads are frozen in our application with the following stacktrace :

java.net.SocketInputStream.socketRead0(Native Method)

org.firebirdsql.gds.impl.wire.XdrInputStream.read(XdrInputStream.java:242)

Any idea to avoid this situation would be welcome.

Thanks
