I'm going through a situation where applications can not connect to
Firebird. At a certain point, suddenly, Firebird does not accept
remote connections.
Connecting locally, via isql, it is possible to access Firebird and
perform queries normally, but not remote. No error messages are
identified in the Firebird log or operating system logs. As a
workaround, we only restart Firebird and it works normally, receiving
local and remote connections. We bserve that if we return Firebird to
version 2.5.0 these issue stop happening.
I have enabled the audit to try to identify what is happening at the
time of the freeze, however in each freeze I observe a different set
of sql commands, there is not indicating what can
be causing the issue and also there are no error or warning messages
on audit log.
Has anyone gone through this or have any suggestions on how can I
identify what might be causing this freeze?
I saw similar behaviour in 2.5.8 on Linux. It is reported as bug
CORE-5757
(http://tracker.firebirdsql.org/browse/CORE-5757?subTaskView=unresolved)
and is fixed for 2.5.9.
For me it seemed to be related to using database events, but the
comments on the bug from the developers suggest it is not related.
I have patched 2.5.8 packages for Debian stretch which you could try.
