The basic problem is 'ulimit -Sn', the number of allowed file handles per process. On Solaris (where I had that problem, it defaults to 64, which is IMHO quite small.) If set this higher, it may solve the problem. But beware that some software isn't written for filehandles being higher that 256 or 1024. For more details on that issue see http://www.rational.com/technotes/clearcase_html/ClearCase_html/technote_344.html. If it doesn't solve the problem, look through the use PERL code for unclosed file handles. It doesn't need to be your code, which is wrong, but some other PERL-Module, you're using. E.g. in my case the trouble maker was File::MMagic. The problem was solved, when I rewrote my code, so that 'new File::MMagic' was used once per embperl page and not once per request: [! use File::MMagic; $CLEANUP{mime_magic} = 0; $mime_magic = new File::MMagic('/opt/local/apache/conf/magic'); !] > Except that I don't have to wait weeks under serious load.

Hitting reload on my > browser usually clears it, if not 'apachectl restart' does. Hitting reload clears it, if the persisent connection from your browser is closed and the new connection is established to a new child, which probably hadn't that many file handles than that one before. P.S.: In this case it probably would be interesting to know about your operating system, 'ulimit -Sn' and 'ulimit -Hn'. P.P.S.: This kind of problems are best debugged with something like 'lsof | fgrep httpd' (lsof = list open files). For Solaris e.g. you get lsof as a package from www.sunfreeware.com, and for Linux it should be included in every distribution.
