Yes,

1) did you use a custom path for the pid file? (using PIDfile directive)

2) you can attach strace to the running process. Like, if 
   interchange is running as PID 1000, you can do:

   strace -f -s 2048 -o /tmp/trace -pPID

   and then invoke interchange --stop. When it finishes, in /tmp/trace
   you search for interchange.pid (or just \.pid) and look up the
   path where IC is expecting it. Then compare that to the location
   where your pid file actually is.

   Btw, strace is a linux command but I think there exists its port
   to solaris. If not, use solaris-native truss command. (See manpage
   for different cmdline args).
