How to debug hangs in multiple subsystems (typically audio and networking)?

I can give system logs for anything, just let me know.

Hardware: Mid 2014 rMBP OS: 10.10.2

“Special” things installed:

• Bartender


• Multiple VPN providers


• Multiple chat/voice providers (plugins for BlueJeans, Hangouts, etc, Skype, HipChat, ScreenHero, probably others)


• Currently switching between two different bluetooth headsets

Here's the list of issues I've been experiencing over the past week:

• Freezing/failing when trying to change audio sources (Bartender -> Volume -> Option Click)


• Mysterious dropping of networking (networking freezes, everything goes offline


• Audio systems switching, dropping, not connecting over Bluetooth


• Bluetooth failing to connect to devices (typically headsets)


• Failure to connect over VPN, typically after awaking from sleep, leads to total failure of networking stack for a few minutes


• Audio failures tend to hang Safari indefinitely until force quit


• Networking failures tend to hang Safari indefinitely until force quit


• Audio Hijack tends to crash / fail to start.

That's the list of issues, and I need some general purpose debugging steps for when a system starts to crash/hang.

• Is there something I can kill -9 and have it restart for a general system (audio/networking)?


• Where are the specific logs for these systems?


• What are typical problem causers (third-party or configuration wise) I can remove or fix?
