Someone wiser than me may correct me on this but I believe this is just a
notice message.
Each thread can handle 126 connections ([expr $threads_maxthreads * 7]) after
which the thread will get destroyed. This is historically done to make sure
any memory leak doesn't take over the machine, so if something was bad in the
thread it would only exist for 126 connections then get destroyed. A new
thread is then created when it is needed, which will also get destroyed after
126 connections.
So that message in the logs is just to let you know the thread severed 126
connections and is being destroyed.

Subject: [AOLSERVER] What does 'exiting: exceeded max connections per thread'
mean?
To: AOLSERVER@LISTSERV.AOL.COM
Hi,
Since we moved to Aolserver 4.5.1, we've been getting alot of these on our
logs: 'Notice: exiting: exceeded max connections per thread'. Does that mean
that Aolserver is receiving more connections than it can handle? If so, what
would you recommend us do? Our servers are running on Debian Lenny 64bit with
3gb ram.
Here's our configurations file:
set nsthread_stacksize [expr 10*128*1024]
set adp_cachesize [expr 512*1024]
set threads_maxthreads 18
set threads_minthreads 1
...
ns_section "ns/server/${servername}"
ns_param directoryfile
"index.tcl,index.tct,index.vuh,index.atcl,index.adp,index.html,index.htm"
ns_param pageroot $pageroot
ns_param enabletclpages true ;# Parse *.tcl files in pageroot.
ns_param maxthreads $threads_maxthreads ;# Tune this to scale
your server
ns_param minthreads $threads_minthreads ;# Tune this to scale
your server
ns_param maxconnections [expr $threads_maxthreads * 7] ;# Max
connections to put on queue
ns_section "ns/threads"
ns_param stacksize $nsthread_stacksize
ns_param mutexmeter true
ns_param maxthreads $threads_maxthreads ;# Tune this to scale
your server
ns_param minthreads $threads_minthreads ;# Tune this to scale
your server
ns_param maxconnections [expr $threads_maxthreads * 7] ;# Max
connections to put on queue
Here's our pools.tcl file:
if {[info commands ns_pools] ne ""} {
set cfgsection "ns/threads"
set minthreads [ns_config $cfgsection minthreads 0]
set maxthreads [ns_config $cfgsection maxthreads 10]
set maxconns [ns_config $cfgsection maxconns [ns_config $cfgsection
ConnsPerThread 100]]
set timeout [ns_config $cfgsection threadtimeout 120]
set spread [ns_config $cfgsection spread 20]
ns_pools set default -minthreads $minthreads -maxthreads $maxthreads
-maxconns $maxconns -timeout $timeout -spread $spread
set cfgsection "ns/server/[ns_info server]"
ns_log notice "default thread pool: [ns_pools get default]"
set minbusythreads [ns_config $cfgsection MinBusyThreads 0]
set maxbusythreads [ns_config $cfgsection MaxBusyThreads 10]
ns_pools set error -minthreads $minbusythreads -maxthreads $maxbusythreads
-timeout $timeout -maxconns $maxconns -spread $spread
ns_log notice "error thread pool: [ns_pools get error]"
if {[info commands ns_limits] ne ""} {
if {[set maxinput [ns_config $cfgsection/module/nssock maxinput]] ne
""} {
ns_limits set default -maxupload $maxinput
}
set maxwait [ns_config $cfgsection MaxWait 100]
set maxwaittime [ns_config $cfgsection MaxWaitTime 60]
ns_limits set default -maxrun $maxthreads -maxwait $maxwait -timeout
$maxwaittime
ns_log notice "default limits: [ns_limits get default]"
}
}
Any help would be greatly appreciated.
Thanks,
Levy Bajamundi
