|Subject||AW: AW: [firebird-support] memory bug?|
actually, we use the superserver with this settings. In the past, we had the classic server, because only it could access to some more cpu cores.
I thought, when we go back to the classic server, the problem with the 2gb RAM overflow is historical, because each of the connection has then an separate memory reservation an this should not exceeded the 2gb. I don’t know, why the superserver despite the limitation increases to more than 2gb of ram.

need to plan for downtime anyway for OS updates etc. Firebird 3.0.1 is
almost 3 years old now (even 3.0.4 is almost one year old by now).
Upgrading Firebird 3.0.1 to a higher 3.0 version is a drop in
replacement (no backup and restore is necessary).
Although keeping the client libraries up-to-date is advisable, updating
the server doesn't require updating your clients at the same time. Older
Firebird clients (eg from 2.5 or 2.1, in theory even 1.0 although I
haven't verified that) can also still connect, but you'll need to
disable wire encryption and make sure that user is created with legacy_auth..

ClassicServer instead? That difference is rather important for your problem..

With SuperServer this is probably fine (256 megabytes per database),
with ClassicServer or SuperClassic, this requires 256 megabytes per

ClassicServer, you should change the page buffer settings of your database.
