I am using tomcat 6 and it has eaten all my memory. > Only 56 Mb reamains. 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? > I have a 2GB memory.

If you were using one connection before, and now you're pooling connections, then you probably are using /more/ memory than before. > As I told there is a [Quartz] scheduler running on every minute. > > Looks > like I have some memory leak. 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). > Otherwise why does my machine uses this memory > this much.

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. ;) > I have not used any tweaks in xml.Should I tune the server to production > mode. What is the solution? Why does not the objects get garbage > collected.? 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? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHFhOP9CaO5/Lv0PARAtb9AJ9E6a+oOpSMWVDTdyMY2I7RYn5U1QCdHgVO BUSCpyDFzkEBOitqqH2UQgo= =pc4x -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
