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' ERR -11608 COMMUNIC sql03_request: wrong connection state, state is 'requested' ERR -11608 COMMUNIC sql03_request: wrong connection state, state is 'requested' ERR -11608 COMMUNIC sql03_request: wrong connection state, state is 'requested' ERR -11608 COMMUNIC sql03_request: wrong connection state, state is 'requested' ERR -11608 COMMUNIC sql03_request: wrong connection state, state is 'requested' 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
