Re: [Quickfix-developers] Deadlock while stopping SocketInitiator and SocketAcceptor

[Dominik B. <dom...@gm...>]

Hi Fabio,
I have the exact same issue here.
I have searched the internet for solutions but I haven't anything except the
old posts from 2005.

The only way I've reliably been able to get around this behavior was to set
the initiator to null and call GC.Collect.
This obviously isn't a nice solution at all so I would be glad for any other
solution.
