I am no a Suse user, so I might ask if Suse 9.1 uses 2.6 Kernel, right ?

IIRC LD_ASSUME_KERNEL should be used to run non NPTL Firebird build on
NPTL linux systems.

If it's not the case I think that will not hurt to remove this
enviroment variable.

I think it is on the release notes, but as I am lazy to search in wich
release notes it is.. I did a quick google search and found this:

* *NTPL problems on higher Linuxen: *The new NPTL (Native POSIX
Thread Library) in Red Hat 9 (so far) will cause problems for
SuperServer and locally compiled programs, including the
utilities. Gbak, particularly, will throw a Broken Pipe error. To fix:

1. in /etc/init.d/firebird
LD_ASSUME_KERNEL=2.2.5
export LD_ASSUME_KERNEL

That takes care of the server instance. You need to have the
environment variable set up within the local environment as
well, so:
2. Add the following to /etc/profile, to ensure every user
picks it up for the command line utilities.
after
HISTSIZE=1000
add
LD_ASSUME_KERNEL=2.25

On the following line, export it:

export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUT_RC
LD_ASSUME_KERNEL
