RE: java.lang.OutOfMemoryError Tomcat4.1.30
Either don't read so large a file into memory (ie read chunks and process them rather than the entire file) or increase the memory that Tomcat can use. You can increase the memory allowed to the VM using the -X arguements (java -X for help). The one you'll want is going to be -Xmx###M where the ### should be the amount of memory you want to allocate. Generally for production servers I typically allow tomcat at least 256 megs of ram using the option -Xmx256M. --mikej -=- mike jackson [EMAIL PROTECTED] -Original Message- From: kjiang [mailto:[EMAIL PROTECTED] Sent: Thursday, January 06, 2005 1:19 PM To: tomcat-user@jakarta.apache.org Subject: java.lang.OutOfMemoryError Tomcat4.1.30 Hi When tomcat (version 4.1.30) read in a large file, java.lang.OutOfMemoryError occurred, what can I do for this issue.

It could just be that your app needs more than the 64m than the JVM initially allots for itself. This is fairly common. Follow Quinton Delpeche's instructions for configuring the memory and watch your app over time with the manager tool. Just remember, the manager tool has limited value. Because Java's garbage collection (GC) doesn't run until the JVM see itself getting close to running out of memory, the memory setting shown in the manager will always climb, even if there isn't a problem. If you have a memory leak in your code, this will only postpone the problem and it, eventually, will happen again, no matter how high you set the memory settings. If the problem continues with more memory alloted, you may want to invest in a profiler to see where it's going. - Ben - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: java.lang.OutOfMemoryError
In addition to Yoav's comment, you may also want to check on the number of sessions that get created. I know that JRun3 didn't create a session when it wasn't necessary to do so, Tomcat 5 (as per servlet spec.) always creates a session. Typically webcrawlers don't 'do' cookies, so a new session gets created for each request. This can of course have a significant effect on memory.

Re: java.lang.OutOfMemoryError
How much information do you put in servlet sessions? How long do sessions last? How many active user sessions do you have at any given time? Do you start the VM up without providing -Xmx512m or something like that? If so, you are starting a VM with a maximum of 64meg of memory available to everything running within it. That includes the appserver itself plus any apps. It is easy to use more than this, especially if your load is high and/or you store lots of info in the sessions. Keep in mind that a little bit of data in the session can go a long way if you have lots of users. Less than 1meg per/user plus, let's say, 64 users with active sessions (not necessarily making concurrent requests) would easily use up the default memory maximum of the VM.

Hi Marco Give 'The Reference Scanner' a try and make heap snapshots and check the diff between snapshots. I just published the tomcat-howto.

RE: java.lang.OutOfMemoryError
I was having a similar problem with a similar configuration but was having to restart every day. For some reason the exact same JDK/tomcat install on my windows dev box performed just fine under stress testing and reclaimed memory just fine whereas my Linux production box had serious issues. I increased the memory from the default 64mb to 128mb on my linux server and now it is behaving just as the prod server does - its reclaiming memory in a similar healthy pattern. So, just try increasing the heap size to 128mb first and see if you're still having the same issue. It seems to work some magic. Cheers.

Sounds like the same memory leak problem I've been having. The problem is when new threads are created to handle concurrent connections.

RE: java.lang.OutOfMemoryError
Howdy, hm..i see...but I am working on a server with 4GB of RAM,I think it should Your server has 4GB of physical RAM, but by default Java will allocate up to 64MB to the heap. You can modify this by using various -X parameters to the java runtime (read up on the Java VM Options if you're not familiar with tuning memory). Many things can cause OutOfMemoryErrors. You can search this list's archives to start with. The person who spoke about connections is likely talking about database connectiosn -- you have to make sure you close all your database objects (result sets, statements, connections) or release them back to a pool if that's where you get them.

RE: java.lang.OutOfMemoryError
You may need to go modify Catalina.bat (I guess that is what it would be on Win2k), add a JAVA_OPT variable, such as JAVA_OPT=-mx512M. I don't remember if it is -mx or -mX though. This will set the highest heap size that the java application can use. You may want to set it to 2 or 3GB though instead. You may also want to use a profiler and see if you have a memory leak in your application.

Re: java.lang.OutOfMemoryError
Hi, I was using the tomcat 4.0.3 with JDK 1.4. Tomcat was integrated with apache using warp connector. I used to have the same problem you have now. I recently upgraded to Tomcat 4.1.12 and warp to mod_jk with load balancing with two instances of tomcat on the same server. Memory usages which used to shoot upto 200 MB in a single day is now restricted to 3-4 MBs a day. I cant not say surely my problem was due to warp or tomcat 4.0.3. Your can try upgrading to tomcat 4.1.12. Raj earlier is now Hi all, I have apache(2.0.39) and tomcat(4.0.4) configured on different solaris 8 machines using mod_jk. I have two instances of tomcat running, each serving different jsp/servlet/bean application. I see lot of OutOfMemory errors in tomcat logs after few hours, some times tomcat totally crashes, if I do not restart.

Re: java.lang.OutOfMemoryError
Hi, Why don't you guys use a Profiler tool like the 'OptimizeIT' which can give you a very clear picture on where the actuall memory toll is!!. We had similar problems when our application was run on 'Apache 1.3.22+Tomcat3.2.2', but finally after a thorough analysis we found that the problem really was on the 'Connection objects'. Please make sure that the connection objects used in the application is properly returned to the pool after use and is killed when the load on the server goes less. This will give an optimum performance and reduce the memory being eaten up by the server. Hope this will fix your problems.. Regards H.Rajesh (Webteam - SSPL) [EMAIL PROTECTED] India.

Re: java.lang.OutOfMemoryError
This is javaVM heap problem. You should increase heapsize.

RE: java.lang.OutOfMemoryError... O happy day.
Tomcat itself doesn't leak any memory as far as our systems indicate. One thing to look at might be session usage - has the orginial developer made the session never timeout (which means that the memory used in it will never be recollected) or jave exceptionally long timeouts? Also, since you can't connect to the database, I would look at that portion of the code, possibly keeping connections open until you use all the database server/license supports? As you probably know, you need to look at objects that grow without being garbage collected (static variables are often times problems, especially Collections (maps, lists, etc)) as well as keeping open IO streams with very large buffers and not flushing them at points of inactivity.

RE: java.lang.OutOfMemoryError... O happy day.
I've just overcome this situation too, and would say my code now has 75% more explicit flush(), close(), and x=null statements, plus make sure you're using hotspot, as gc on hotspot seems to be 1,000,000,000 times more effective I *know* what you are going through, don't give up youwill win in the end. in my case I ran out of memory after about 2-300,000 hits. now it sits happily on a test set-up at 19-24% memory use, 84% cpu load serving 12 clients 2 hits per second each, day in day out no complaints. d. ;-) -Original Message- From: Randy Layman [mailto:[EMAIL PROTECTED]] Sent: Monday, April 16, 2001 6:50 PM To: [EMAIL PROTECTED] Subject: RE: java.lang.OutOfMemoryError...
