trace of Apache 2.0.38 with the worker MPM on Solaris 8. This trace was collected using: truss -l -p httpd_child_pid. The -l option tells truss to log the ID of the LWP (lightweight process-Solaris' form They all produce similar output. In this trace, a client has requested a 10KB static file from the httpd. Traces of non-static requests or requests with content negotiation look wildly different (and quite these in a system call trace, because the httpd uses custom memory allocators (apr_pool and apr_bucket_alloc) for most request processing. In this trace, the httpd has just been started, so it must call malloc(3)
