The version I use is valgrind-3.7.0.SVN. > 2) Which hardware and operating system (and version) are you using? > If Linux, then report the output from running "uname -a". The operation system is Fedora 12. The output of "uname -a" is the following: Linux localhost.localdomain 2.6.31.5-127.fc12.i686.PAE #1 SMP Sat Nov 7 21:25:57 EST >> So I think maybe it is the unhandled syscall or the unhandled >> socketcall that fails the starting up of http server, which in turn >> causes the timeout problem.
