I was reading about a new perl module, Devel::Trace::Syscall which can be used as a perl debugger module to print stack traces when certain syscalls occur (perl -d:Trace::Syscall=$ARGS $SCRIPT).

There are a few more nice strace blogs posts by Julia Evans. One of the ideas I’d not thought of before is using the -c option (count call time) to assist with troubleshooting performance (which is mentioned here among other places.
