Well - It might just be a flaw in our code/design that is eating resources away unnecessarily. It's just strange that
it'sthe driver and not the server crashing and that older versions of psqlODBC seem to work fine.
> BTW how big is the size of Commlog file?
The Commlog is about 70 MB. I'll do another run with psqlodbc-08_00_0101 myself to make sure that this version really
doesnot crash on this db. I noticed that quite a few cursors are declared with hold (but also released) during the run
ofthe problematic application. The encoding of the data bases is LATIN1. Yesterday I detected lines with characters not
definedin LATIN1 in the dump. I'll check on this as well.
> Anyway could you put them somewhere where I can dounload it?
I've asked our admins to set up an account on our ftp server for you. I'll send the login information to your private
emailaddress as soon as I get it or do you maybe have a ftp server where I can upload the logs? If psqlodbc-08_00_0101
isnot crashing should I try to let the run be logged in Mylog and Comlog?
Thank you very much,
Peter
