Re: [WEB400] Hit capacity of Classic HTTP Server and a module 170

["Jim Franz" <franz400@xxxxxxxxxxxx>]

Bob - what are you serving?  static html or dynamic? lot's of pictures?
How much memory in the 170? what's the cpw?  any heavy sql or rpg
processing?
I've got a customer with a S10 512 meg 73 cpw serving rpg cgi
that sometimes hits this volume. Only have a performance problem when
some sql queries have to roll thru all records in a big file (where x like
%yy%)
but never crashes.
Are you saying crash as in restart the server? Did you get any job logs of
some other problem or just timeouts?
