Well, the good news is that I've solved my problem, and it's not related=20
to Python LDAP at all. :-).

 I wrote a small C-program that also reproduced the same problem. So,=20
this narrowed it down to a few things: C-compiler, glibc or kernel. I=20
hadn't touched the first two in quite a while, but I did upgrade the=20
kernel a week ago... So, I rolled back to 2.4.7 (from 2.4.17), and now=20
my problem is gone. Don't ask me what happend with the 2.4.17 kernel, I=20
hadn't noticed any problems or errors at all after the upgrade (RPM from=20
Rawhide), but something is not good...

The module still leaks memory though, I'll poke at that little later.=20
Thanks again for the help, so I could narrow things down to the real=20
problem. :-)

Thanks,
