Subject RE: [ib-support] Events, Firebird 1 and crash
Author Tasos Kyriakos
I had the same problem, three months ago, i send some messages but no any
The problem was with
-DBase Server: FB 6.01, IB RC2 and FB 1
-Server OS: Win2K Pro, NT Server 4 sp6, Win98
-Client OS: Any Windows from Win98 and upwards
-Programming tools: D5 Ent, IBX (last vesions)

The appl used to use ib events. if the access to FB Server was ONLY through
Local Network
all was OK. BUT when a connection through a remote connection was trying to
register events the server was crashed every time, immediatery, without any
notice in log or everywhere else
and the only way was to do full restart of OS...
I dosn't managed to find any. So, I just changed the program (for remote
connection) in over to not use events.

I hope it will be found now a more usefull way to "solve" problem.

Subject: [ib-support] Events, Firebird 1 and crash

Sorry to bother you if this has been answered, but could not find an
ANSWER just ideas.
Some have complaints that Firebird crash upon registering events from
delphi apps
and tibevent. They often have a configuration of either server or client
with multiple
nics or interfaces.

I don not - one NIC at client and one NIC at server end.
Registering events -> crash of Firebird without notice or error handling
at server side.
"Unable to complete network ....."

Not registering the events -> everything works.

Local connection works, but no remote connections.

Client: Any Windows machine with D5 app using latest IBX and gds32.dll
from FB 1.
All machines in hosts-file

Server: FB 1 SS on RH linux 7.2 default networking with one NIC and
local interface lo(in that order).
All machines in hosts-file. No firewalling

Everything else(but not Events from remote clients) works every time.
So an application without events - no matter how complex in terms of
queries and tables
works flawlessly.

I have seen guesses about gds32.dll and specific ports for events and
ideas that traffic
is confused by multiple interfaces. Well, it's not that in this case.

And - I can reproduce the failure with 100% accuracy.

Ideas anyone?
