SunOS moses 5.6 Generic sun4u sparc SUNW,Ultra-2      
I encountered the following problems with Apache 1.3.3 during
a mass test (about 250 mostly parallel wgets on the same URL):

- in one case Apache stop serving any request with the following message:
[Wed Oct 21 11:42:10 1998] [error] server reached MaxClients setting, consider raising the
MaxClients setting
  I had to restart Apache after this message

- after increasing the number of maxclients I got lots of messages:
  Wed Oct 21 11:42:33 1998] [crit] [client] (13)Permission denied: /home/.htaccess
pcfg_openfile: unable to check htaccess file, ensure it is readable
  Why will Apache look in /home/.htaccess ? Serverroot und DOcumentroot are somewhere deep
under /home !

- if Apache is started with -X I see MORE than one httpd processes although
  the documentation says it is running in single-process mode

   moses@/home/ajung/testbed(54)% ps -ef | grep httpd
