Subject Re: Firebird freeze on Ubuntu
Author pdhakan
Hi Helen,

I tried both the options that you suggested.
The build with NPTL frooze in under a week.

Is there any other thing that can be done?

Yup. You need either the NPTL build of superserver, or to set
LD_ASSUME_KERNEL=2.2.5 in your environment. Exact instructions for this
are on p.57 of the release notes (in the doc directory).

You'll find the release notes essential reading for this and lots of other
