Hi,
just from gut feeling: this sounds like an improper synchronization in the
application layer. Maybe you're using the same connection from two
different threads at the same time. Just my 0.02EUR.
Im am completely sure that I dont do this.
But thank you for the hint,
By the way: What does the Garbagecollector with unclosed connections?
Does this anybody (Daniel Dittmar :-)) know?

Hello all,
We are using a multithreaded python application as a middleware
to the database.
sometimes (when many clients are working intensively at the same time)
I get the following error to the console of the server:
ERR -11608 COMMUNIC sql03_request: wrong connection state, state is
'requested'
ERR -11608 COMMUNIC sql03_request: wrong connection state, state is
'requested'

The main python process (we are using python 2.2.3 on a suse 7.3 system
which uses libpthread)
suddenly disappears (gets killed because of an evil error in the python
driver?)
We are using
- sapdb-srv74-7.4.3.27-1 (database is on the same server like the
middleware)
I suspect a problem with the thead-safity of the python-driver.
Additional information:
- Each thread has its own connection-object
- Threads do *not* share connections or cursors
- before opening or releasing a connection we aquiere a threading.lock.
What could the problem be?
Does it help if we upgrade the database server to
7.4.3.32?
Thank you very much in advane for your Help.
Greetings, Andre' Reitz
