RE: [Quickfix-users] QuickFIX becomes unresponsive after running for some time...Please help

[<vi...@ma...>]

Hi,

Thanks for the quick response.

The version we are running already have this
change!!

We could trace the problem to the way threads
were accessing Sessions.=20

When Session.sendToTarget was called directly=20
from callback onMessage, somehow a deadlock
was getting developed.

Instead, when we launched a separate thread to
make call to Session.sendToTarget, allowing=20
onMessage to complete quickly, it started working
fine...

Could we get a DOs and DONTs using QuickFIX engine?

Thanks,

Vivek

This is probably the race condition which this patch
fixes:
