Hi,

I have an Issue with the IBCAlerter.
Using FB 3.0 & IBDAC 5.7.25

When connecting and reconnecting to the Database everything works fine. But after some time the ibcalerter doesn't respond to any event anymore. But i don't get any exceptions or causes for this. It just stopped to fire any events.
Active property is still "Active" and Event list is still filled. Autoregister does not help with this issue.

To call Stop and Start or Disconnect and reconnect solves this problem, but i cannot get any information about the state of the alerter. So calling every hour start & Stop is not a solution for me. In worst case important events will be missed.

To reproduce this, just connect a ibcconnection with a alerter to an db and register "TEST".
With a timer call a procedure wich just calls POST_EVENT "TEST" in the Database.

After some time (20 minutes to 6 hours) the IBCAlerter does'nt call any event, but keeps being "Active".
No Exception is raised or Information about the connection state of the ibcalerter is given.

Unfortunately, we could not reproduce the issue.
In order to get a detailed answer, please compose a small sample demonstrating the described behavior and send it to viktorv*devart*com, including scripts for creating database objects.

After some investigation it seems to be a Bug in the Firebird Server and FBClient.dll

Since FB 3.0.1 is now released the problem doesn't occour anymore

It is good to see that the problem has been solved.
