If you can afford running in a single server mode[1], then you could record all the requests and then reply them [2]. If you can't then set up a testing server (unless you have one already) and try to run requests randomly. Another approach is to simply open a different filehandle for each childprocess and write each request there. Use $$ to differentiate between the processes. In any case make sure that you use the latest mp2 version (1.17 as of this writing) and in the future always report problems as explained here: http://perl.apache.org/bugs/. Thanks.
