Thank you for response!
I just want to run callgrind for profiling to catch the slow parts of specific module of httpd.
Can you please send me those specific options which may fix my problem?
In addition after some time work valgrind prints out a lot of following messages:
Thread 299: status = VgTs_WaitSys

and exits with following message:
Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what Linux distro you are using. Thanks.
Looking forward to hear back from you soon.
Thanks in advance,
