Hi there

I am trying to use a Sybase ASA 64 bit databaseserver on an 64 bit machine, 
but have problems with it.

Platform:

$ cat /etc/debian_version
4.0

$ uname -a
Linux nikko 2.6.18-5-amd64 #1 SMP Sat Dec 22 20:43:59 UTC 2007 x86_64 
GNU/Linux

$ cat /proc/cpuinfo
processor       : 0
vendor_id       : AuthenticAMD
cpu family      : 15
model           : 33
model name      : Dual Core AMD Opteron(tm) Processor 270

(snippet, 4 cores in total)
