am I correct that that would be done like so?:
strace -p <process id of php deamon>
Im a little new to this kind of coolness, I found this page which is very
helpful:
http://www.ibm.com/developerworks/aix/library/au-unix-strace.html
I was going to suggest using gdb to figure what the process is doing but
figured it
wouldn't be handy to have the deamon running via gdb for 48 hours ... silly me
didn't
grok that you can attach to an existing process (something that ibm article
made clear
to me)
can't wait till my macbook arrives so that I can start to play with this kind of
stuff locally ... aka another excuse to justify the aluminium beast ;-)
