 New Comment:

It seems like your realpath cache isn't working at all.



Could you set a breakpoint on realpath_cache_find and step into it the
second time 

it hits those stat calls.  Does it go into the while(bucket) loop there
at all?

I don't see that here.  Attach gdb and set a breakpoint on lstat and see
who is 

calling them.

I have already tried with 5.3 and I was thinking to open an new bug
because I have same behavior, there is only a change in the order of
execution of lstat from fullpath to /usr :



7339  chdir("/usr/local/myspace/webspace/httpdocs") = 0
