Re: [Quickfixj-users] Multi-threading/blocking question

[Joerg T. <Joe...@ma...>]

Hi Tommy,

some time ago there was an issue with cross-blocking threads for a FIX bridge sending messages forth
and back between two sessions directly in the fromApp().

There is no extra queuing in QF/J, but I know that there have been some changes to split larger
critical sections to smaller ones to reduce the chance of deadlocking.

Cheers, Jörg
