[Pgpool-general] Pgpool I vs Pgpool II

[Glyn Astill]

Hi takizo,


Yes this bug has been seen by numerous people on the list, Yoshiyuki Asaba has posted a patch, however there has been no response from the main Pgpool II developers.

I did ask a few times, and also asked if we'd be better testing 3.1, but alas still no response.  I can only assume the devs are busy or otherwise indisposed.

See the thread below for the patch.

>Hi all,

>Today I have upgraded Pgpool I to Pgpool II. And I had to roll back to Pgpool I due to memory hunger issue.

>My server is configured with 
>PostgreSQL 8.2, 
>running on FreeBSD 8.2
>Intel Xeon box with 4 CPUs with Quad Core, total of 16 cores
>Memory with 24GB

>* While running on Pgpool I
>I do no have
 memory hunger issue.  On postgresql.conf, I have max_connections=200 and shared_buffers=2GB. 
>Most of the time, I have 8GB memory in used and 10GB Free and some in cached. Everything run just fine and perfectly good. 
>
>* I tried upgraded to Pgpool II 
>Same config on postgresql.conf, when I started PgPool II (3.0.4), my active memory started increasing and it didn't drop at all. 
>I left the server running and after about 20 minutes, 20GB memory is in used, ended up it used swap memory because running out of memory. 
>
>I run a reload/restart on pgpool, I gained back 14GB of free memory, and slowly it started to taken up those freed memory in active memory after about 15-20 minutes. 
>I tried to bring down max_connections and shared_buffers value, and the memory doesn't stop taking up. It still slowly gaining all the memory it wants. 
>
>Has anyone having that problem as well? I hope I can find some answer here :) 
>Wanted
 to try out pgpool II performance but this problem is the stopper for now. 
>
>Hope to get feedback from gurus in the house.
>
>Thanks!
