Hi Philip,
That seems like too much memory per httpd.
Does the memory usage grow overtime, or is it static?
If it's static, then the BIG data structure(s) you're storing in
RAM may need to go to disk.
If it grows over time, maybe a data structure is unintentionally
being treated as a global variable --- because the variable persists
between requests the data structure may keep growing and growing.
The solution may be to lexically declare the variable with 'my' so
that it only survives for the scope in which it is declared.
If there is no programming solution ... you can also set the
MaxRequestsPerChild in httpd.conf so that after a certain number of
requests the child dies and frees its memory.
