Hi all!

I'm using pound on a high traffic site with over 30 million daily hits (~750000
unique ip's) using three backends and session (cookie) persistence with a TTL
of 900 seconds.
Pound (tried both version 2.5 and 2.6a) is installed on a dedicated linux
server (kernel 2.6.28) with 8Gb of RAM and 1Gb of swap.
I notice pound's memory usage increases daily until filling all swap space
(vm.swappiness is set to 10) after about a week:

# ps aux|grep pound
nobody   17623  0.0  0.0  50040   300 ?        Ss   Sep09   0:00
/usr/sbin/pound -f /etc/pound.cfg -p /var/run/pound.pid
nobody   17626 16.3 32.9 3518264 2692924 ?     Sl   Sep09 1875:30
/usr/sbin/pound -f /etc/pound.cfg -p /var/run/pound.pid

As you can see it's using over 3.5Gb of virtual memory and still increasing...
As workaround I can restart pound periodically but i wonder if there is
something wrong that can be fixed.
Please let me know if you need more information about this issue.

Thank you!

Ok, I've found the answer:

I had tcmalloc installed but it wasn't meant to be used with pound but with
mysql (it give it a huge boost).
Uninstalling it and rebuilding pound solved the memory leak but in my humble
opinion it would be better to add a configuration switch instead of linking
against tcmalloc by default.

Adios.
