[Valgrind-users] How to run cachegrind on a process that doesn't exit

[Joy V. <joy...@gm...>]

I have a program that I would like to profile with cachegrind, but this
program listens to a port an really only exits with a kill comand.  I cannot
get cachegrind to dump the profile information.  Is there an option to
incrementally dump profile info rather than on exit?
Thanks.
