When it loses connectivity the application is taking a long time (8 - 10 minutes) to re-establish VPN network connectivity, despite the fact that other applications can see the VPN far sooner (roughly 2 - 3 minutes). From our application logs we can see that two ...

Even though threads and thread-safety are not really new topics for me, I found out designing a new multi-threaded application is probably half as difficult as trying to tweak some legacy code. I skimmed through some well known books in...
