Hello,

Running FB1.5 as a service and a threaded application on same computer using
Tcp/ip
to localhost:drive:\path\fb.gdb causes the main thread to freeze a couple of
times a day.

Replacing FbClient.dll by FbEmbed dll in path of application and using just
drive:\path\fb.gdb
resolved this problem and application now running for days. But now only one
application
can use the database, since the local FbEmbed/Alias FbClient locks the
database.

Any ideas ?

Best Regards,
Hans
