This problem occurs when the client and server is behind a firewall.
If the server can´t create a second connection in client, freeze.

The event service in client side acts as a server!!!!
In server side, ibserver try to open a new connection in a port other than 3050, defined by client!!!!!
Therefore, if this new connection fail, ibserver freeze!!!

It´s a big bug.

The problem is somewhere in Linux - I had (have) precisely same problem, and
it occured after I upgraded from RedHat 6.2 to RedHat 7.3, and no help from
RedHat 8.0. This was IB 6.01, so I hoped to solve problem by switching to
FB, no luck, as you know. The really ugly part is that IB events
registration locks-up the FB/IB server. The only fix is re-booting the
server. (Yes, I'm talking about rebooting a Linux server). Solution - there
isn't one, and no matter what group you go to, you will be scolded for
posting the message. Post it somewhere else.

Your only hope may be to get IBX code (hah!) figure it out yourself. Let me
know, I want the fix too...

I guess I'll save Helen Borrie time for writing one mail, if I write
you, that this list not for problems with beta versions of Firebird.
Send it to firebird-devel list at sourceforge. ;)
