On my bookmooch.com site, I'm noticing that my nsd process adds about
300mb of memory usage every day, requiring a restart once a week
after I approach my 2gb memory limit. I'm trying to fix this.
One theory I have is that the Tcl interpreters are slowly bloating.
A simple test.adp page I made with a bunch of tcllib package
requires, followed by package forgets, slowly bloats up.
Apache mod_perl deals with this kind of problem by occasionally
killing an interpreter and reloading it. Is there an automated way to
do the same thing in Aolserver?
I've written this function below, which uses ns_markfordelete and a
namespace global to kill the current tcl interpreter every 100 runs.
namespace eval runtimes {}
proc check_if_should_cleanup_interp {} {
global runtimes::runcount
if {[info exists runcount] != 1} {
set runcount 0
}
incr runcount
puts "Tcl Interp run count: $runcount"
if {$runcount > 100} {
puts "marked tcl interpreter for deletion"
ns_markfordelete
}
}
