    It means you should ignore those messages. 🙂

    Every message contains a Process ID (pid), which is the value within the parenthesis. Those messages are coming from pid 34; it’s highly unlikely that your process is pid 34.

    You can use adb shell ps to get a process listing.

    For example, on my Nexus One, I see:

    W/AudioFlinger(14104): write blocked for 172 msecs, 901 delayed writes, thread 0xea50

    What’s pid 14104?

    $ adb shell ps | grep 14104
media     14104 1     23992  1996  ffffffff 00000000 S /system/bin/mediaserver

    /system/bin/mediaserver is certainly not an app you should be overly concerned about. 🙂

    How do you determine the pid for your Mono for Android process? By looking for the process startup message. During process startup Android will list all ContentProviders it’s loading into the process. Of interest is the __mono_init__ provider:

    I/ActivityThread(  602): Pub TouchTest.TouchTest.__mono_init__: mono.MonoRuntimeProvider

    The above message comes from your Mono for Android process, so all further messages with pid 602 (in this case) will be messages from your app; you can freely ignore other pids.
