Try to use valgrind’s callgrind tool for investigating where the time has been use.

I can't post source code. Maybe later I will make simple version of server, which can reproduce timeout errors.
I can reproduce errors only on big count of real users requests, so ltrace/strace output will be huge and not useful.
I've enabled -DUSE_DEBUG and got a lot of debug information.
I have 3 lines of output in my httpserver log for one request. I am looking output only for timeouted requests.
2011.08.11 13:34:20 v[3] handler_input: id: 11205565 # --- uniq ID of request
2011.08.11 13:34:20 v[3] handler: id: 11205565 ip: X.X.X.X uri: /query/xxx/yyy/ # --- IP and URI
2011.08.11 13:34:20 v[3] handler_output: id: 11205565 # --- uniq ID
How can I figure out which debug lines from libevent corresponds to this one request?
