Hi, We are using the standard CPAN module, Devel::NYTProf::Apache for profiling our mod_perl App. We have set it up as follows :
1) Inserted "PerlModule Devel::NYTProf::Apache" in httpd.conf file. 2) Restarted Apache with a Single Process with the command line option -X. Then, Apache 'Segfaults' (Segmentation fault). As a result I used Core dumping with Apache and checked with 'gdb' but nothing useful found(Perhaps there is more to check that I am not aware at the moment). Note also that, 1) we restarted Apache normally(with more than one child processes), then it just 'runs' as usual and when I checked the Exit Status, it was normal(0), but there was no httpd processes running. 2) I checked with both NYTPROF variable set and without setting it(in which case it will default to /tmp/nytprof.$$.out). 3) checked with various trace levels, when it is zero it segfaults asap, if it is 1 it prints some then segfaults and if it is 2 it prints some more then segfaults, etc etc. ( I checked upto level 3 of trace so far.) Thanks and Regards Mohammed.
