I also experienced the same problem with DBD-Sybase.
I've investigated around and gotten the following results;

The problem always occurs when we use any program which
is linked with the FreeBSD native version of open client library on
FreeBSD 4-stable or 5-current. However, this problem occurs only when
a server and a client is on the same host.

A client on FreeBSD 4-stable or 5-current can connect to the ASE
server on any different host such as 3.4-RELEASE, 4-stable, 5-current
and even Linux or Solaris with no error.

On FreeBSD 3.4-RELEASE, there is no problem.

It's very funny.

I've being debugging using gdb and devlib, which is included in
sybase-ocsd-10_0_4-FreeBSD-6_i386.tgz, but I've not be able to get any
useful information so far.
The problem may be in FreeBSD not the Sybase library?

In summary, we should run a client on the different host from that a
server is running on if we want to use FreeBSD 4 or 5.

Does anyone has any other experiences or knowledge about this problem?
