Subject Re[2]: [firebird-support] Classic to Super Server
Author André Knappstein, Controlling
Hi Mitch!

If it's Windoof you're installing it on then mind the zombies!

FB 1.5.x has a problem with connections kept alive, resources kept
reserved. Only affects CS on Windows, not SS on Windows, not anything
on Linux. I reported that and it finally was proven an existing bug
and was fixed in 2.x, but not backported to 1.5.x.

Those zombies won't harm me on the old 1.5 CS I have, because I know
the maximum amount of resources for the highest possible number of
zombies in our company, and that server is fit for that.

Can be bad though if the highest number of possible connections
exceeds the abilities of your server.

ciao,
André
