ILA Adapter dies shows 'RED' ball, Why?

We are running the ILA adapter on a Sun Solaris 8 box and in the adapter_trace log files , we are seeing the following:

9:41:20 AM CST.608 [Monitor] (102) Adapter process “BVILA”: terminated with status 0

3:23:22 PM CST.631 [Monitor] (102) Adapter process “BVILA”: terminated with status 15

Can anyone explain these status Codes to me?
