If you're able to use dtrace, it would be useful to try tracking
allocations with the solaris tag:
# dtrace -n 'dtmalloc::solaris:malloc {@allocs[stack(), args[3]] =
count()} dtmalloc::solaris:free {@frees[stack(), args[3]] = count();}'
Try letting that run for one minute, then kill it and paste the output.
Ideally the host will be as close to idle as possible while still
demonstrating the leak.
