This holds with the one thing I did find on the net. Apperently this is new to the 2.4 kernel and has a Theoretical limit of 32768. I would guess that this means it hasn't been tested above this limit. And thanks loads for the link and info.

Re: [expert] Forte for Java on Mandrake 8.1
hi list it just so happen that i am currently researching about threads-max when i saw this thread on my mails. the internet sources say the computation for thread-max is ((RAM * 1024 * 1024) /8192)/2 check out: http://www.linuxjournal.com/article.php?sid=3814 however, on actual experience, i have a web/java server with 2 GB RAM and the default thread-max set is only 32768. if i should use the computation above it would be way more than 32768. it seems that it is assumed (by the kernel developers) that 512 MB RAM is the max RAM which is why even if i have more than 512 MB, my thread-max was set to 32768. or maybe they think that 32768 is the max that is still workable for the linux OS. i really dont have any idea about that. im not sure how its gonna affect the system by setting the max thread to the computed value or at least double the current default. anyway, i am gonna make some tests to see if its gonna make the java apps perform better or if its gonna kill it. hope the info above sheds light on your queries about the computation. cheers, dianne --- damian <[EMAIL PROTECTED]> wrote: > El vie, 15-03-2002 a las 16:52, James escribió: > > On Fri, 15 Mar 2002 09:47:14 -0500 > > Bill Davidson <[EMAIL PROTECTED]> wrote: > > > > > Now I'm curious.

I looked into /proc/sys/kernel/threads-max the number was 3063 (I hadn't set anything here and was curious so this is a stock number) Then since my ram was larger and the stock number was larger I divided 3063 by 384 and came up with (rounded) 7.98 when I did 1024 divided by 128 I got 8 so I assumed (lousy idea but I did it anyway) that the ratio is around 8 x ram = number in /proc/sys/kernel/threads-max.

Re: [expert] Forte for Java on Mandrake 8.1
Raffaele, Your letter is one of those that peeks curiosity. I looked at my box (running 384 megs) and found that the number was 3063 you said you had 128 megs and 1024 ... The ratio seems to be about 8xram in megs don't know what this means or why it's set to this but maybe this will help.

[expert] Forte for Java on Mandrake 8.1
I had problems running a fairly big applet in the Forte for Java 3.0 with JSDK 1.3.1: the IDE started ok, but when I tried to execute the applet I got an "out of memory" error (on a 128Mbyte machine). I found out that for some reason the threads-max kernel tunable was set to 1024, which turns out to be too small for the IDE. [is this a default for MDK 8.1, or was it changed when I played with the security things?] Changing to 32K with # echo 32768 > /proc/sys/kernel/threads-max fixed the issue. bye, raffaele - italy Want to buy your Pack or Services from MandrakeSoft?
