Thanks Campbell and Grant for your inputs.
Just to add that. It was intermittent issue in the beginning but now the
issue is serious as we were not able to process the trades at one go.
Our product is a 64 bit application.
Is QuickFix.dll a 64 bit or a 32 bit ?
Will there be any fix for this ? so i can download the updated dll ?
Thanks,
