Native Library Not found

That worked finally with the increase in PermGen space.
Filip,
I am a bit concerned about my server memory.
See my top (not mine ofcourse)

See Mem: line and see the second one . It rises so fast  . See at what rate.
429424k
475488k
509384k
518932k
536952k
So at the end of the day, it will be end of the server :-). End Of Servers ,
can be a new film.

What is this PermGen space. Why does not it get garbage collected.
Is there anyway  I can tell tomcat to suggest the VM a garbage collection
more often than the default garbage collection algorithm does. Is there any
declerative way of doing, xml, .sh?

Thanks

[Aru]

And finally after 2 days of struggle I got my new server up.
Check ibaaz.com, that is what I was trying to bring up. Thanks for the help.
Being said that, I am going to use a heap profiler to see what is happening
in JVMs head.
And see if I can match its intelligence.

Why I did not test this before is because, I donot thought this was a
soultion though. Tomorrow another developer add something to the product and
there we go. I will be asked "Hey guy increase the memory of the server,
that may be the problem, last time it was!!". Then I might need to empoy a
guy to do that . ;-)
But now I think some programs just needs more memory..
But I have a question to ask you guys. Should not the tomcat server handle
my webappliations memory request. Its not a huge weapp. Its just a simple
product and my memory request are handled well by my local tomcat.I did not
tweak any xml or .sh, both on my remote server and on my local server.
Is it a reason of different versions of software running. I do not think
there is a compatibility issue with jdk and tomcat anyways. The problem
could be because the default VM setting for tomcat in windows is different
from the default VM settings in Linux. Thats my conclusion after all.

Well, look at the CPU consumption at the same period - so your Tomcat
is working on something. Looking at the amount of CPU time consumed,
it could even be still running the application startup (Tomcat by itself
can take something like 20 seconds of pure CPU time, on some machine
architectures at least -- and here the CPU time usage is running from
13 to 48 seconds - so it's still too early to say whether the rise
in memory usage will continue or not).

> What is this PermGen space. Why does not it get garbage collected.

PermGen is the holding space for the program code in your currently
active classes. So, looks like whatever you're using has quite a large
active codebase.

Even PermGen is cleaned in current JVM versions -- but classes can only
be unloaded when there's no reference to the class within the JVM.
And garbage collection overall is done when needed: it is definitely
done before JVM throws an out of memory error. There's quite a lot of
tunables for the JVM (including garbage collection), but pretty much
you should trust the defaults (unless you have experience to actually
distrust the defaults because of some specific feature in your application
or runtime environment).

This is my machines top. I am using tomcat 6 and it has eaten all my memory.
Only 56 Mb reamains. I have a 2GB memory. I have added a connection pool
using commons-dbcp and thought that will reduce the probs. What is your
suggestion. As I told there is a scheduler running on every minute. Looks
like I have some memory leak. Otherwise why does my machine uses this memory
this much. I have an autobuild script running everyday which checkouts from
sourceforge cvs , stops the servers, build it and redeploy and start tomcat.
Yet , today I looked at my machine , and Ah ! here we goes.
I have not used any tweaks in xml.Should I tune the server to production
mode. What is the soultion ? Why does not the objects get garbage
colllected.?

Actually, the java process is only taking 285MB of physical memory. The
process has allocated just under 1GB of memory, but is not using it at
all (since virtual - resident cannot possibly fit into your 108k of used
swap, you can tell that nothing has been swapped-out).

Some other process has the rest of your 2GB physical memory tied up. top
even tells you that your java process is only taking up 14% of your
memory. What's the problem?

How many connections do you have configured? If you were using one
connection before, and now you're pooling connections, then you probably
are using /more/ memory than before.

Maybe, maybe not. Does your application eventually crash? If so, how? If
you turn off the scheduler, does the memory problem go away? What does
Java report as the free/total/ma heap values (hint: look at the
java.lang.Runtime class).

So, you are experiencing an OOM before an entire day goes by? Wow. I've
never heard of rolling reboots on non-MS-Windows machines. ;)

You have received many, /many/ suggestions from other posters as well as
myself. You have followed none of them. We ask you to provide more
information and you do not. Instead, you notify us that you are trying
some other strategy (switching JVM version, etc.). Finally, you changed
your PermGen heap allocation and everything was working again.

Are you saying that now you are having problems again? Or, are you
simply worried about the amount of memory taken by your application?
Java applications simply take up a lot of memory. Complex applications
take up a lot of memory. Complex Java applications take even /more/
memory. Webapps count as complex applications. Maybe you just need a
bunch of RAM to run your application. Have you considered that?

Ok,
I have taken all the posts seriously. I have not ran into a solution. Let me
work on the suggestions you provided. I  resolved the OOME , but I am
worried about scaling users in my server, if  tomcat consumes this much
memory.  As you said since tomcat is not taking the memory  I will further
investigate as to why the memory gets used this much. Thanks again for all
the help provided. Sorry for me being so obtrusive.
