[Python-sybase-misc] cursor.close() hangs

[Christophe C. <cc...@fr...>]

Hello,

I'm new to this list, and I'm currently trying to access an old windows Sybase 
ASA 7.0 from python/linux. I could make it work with freedts, but it hangs on 
some operation:

 >>> db=Sybase.connect(...)
 >>> c=db.cursor()
 >>> c.execute('select * from rue')
 >>> c.fetchone()
(...)
 >>> c.close()

here it hangs, nothing happens, with 0% CPU.
It only exits if I stop the database server:

Exception Sybase.DatabaseError: <Sybase.DatabaseError instance at 0xb7cf47cc> in 
<bound method _FetchLazy.__del__ of <Sybase._FetchLazy instance at 0xb7cf4e4c>> 
ignored

What is the recommended way to investigate this?
Did anyone have the same problem or is it trivial?

thanks,
Christophe
