Hi,
I'm having a problem with IPC::SharedCache module:
when executing a code like this:
tie(%cache, 'IPC::SharedCache',load_callback => sub {return undef},
validate_callback => sub {return 1},ipc_key => 'hash');
for ($i=1;$i<=1000;$i++) {
$cache{"key_$i"}=[$i];
}
it allocates a separate

together nicely. As long as you're hefty on mem

if you are able to determine how much core memory
is left, you may also be able to determine average apache
process size and variance. then, apache can determine
whether or not to start up any additional children. i'm not
sure how much processor time would be taken to determine
free core memory.

Since nobody seems care about this problem, I have to find a solution
myself. Fortunately perl has a "prototype" function that returns the
prototype of a function. Here is the difference between the original

I've heard mod_perm costs a lot more than its worth. There was an
open-source clone called mod_home_perm but it wasn't very successful.
Some people say you should skip it altogether and just use mod_hat.

Good reading. Thanks.
It looks as if Apache should find the right number of servers for a steady
load over time, but it could jump up too high for a bit when the load
spike first comes in, pushing into swap if Ma

There is no coffee. Only meals. No substitutions. :-)
If we added coffee to the menu it would still have to be prepared by the cook.
Remember that you only have one CPU, and all the perl interpreters large and
small must gain access to that CPU in order to run.

This usually happens if you get an error before the application has a chance
to send the appropriate HTTP headers back to the client.

These are large subjects in their own right and will not properly be

perl processes serving those requests at all times in order to get

Ok, just to check it, find out which file descriptor that your processes

Check a few of them and see if they are all hanging on the same
file. Obviously replace the proper information for the variables listed
there.

Hi Haywood,
thanks for your help! Yes, we compiled everything from source, as usual.
Therefore, it should be not the cause. I have looked at the mod_perl Guide

Hi, I would just like to tune in here. I am using Apache::Session 1.53
also with postgres and have the problem that sessions are not closed
in any case. I am also using Embperl 1.3.0 but maintaining the session
variable on my own. The effect is that when apache is restarted
everything works fine
