How to remedy "AX Lookup problem!"?

[Nikk]

When running a test I will sometimes get the AX Lookup problem line, which means my test will fail. Log output of a failing run:

2014-05-07 14:33:38.775 sim[97900:303] Multiple instances of launchd_sim detected, using com.apple.iphonesimulator.launchd.2a71552c instead of com.apple.iphonesimulator.launchd.3e0456a8.

Immediately after, with no changes to the code, I ran the same test again and it worked without problem:

What the heck does "AX Lookup problem! 1102 com.apple.iphone.axserver:97892" actually mean?

How can I avoid this silliness happening?

Thank you in advance!

Seem to be instruments bug. I run into this many time too.
