Java jvm server mode memory leak out of memory crash

Hi,
I am using java version "1.6.0_13" on a windows 2003 server.
I am running apache-tomcat-6.0.18 PermSize:256M HEAP:1G
If tomcat is started with java with client mode vm, the site works very well!
Requests are processed without problems and memory heap will stabilize on 500M.
I like to use the server mode. If I start the tomcat with server mode, then
the web application work better (30% faster), but memory heap will increase
increase more than the 500M about the 1G and then the tomcat process crash.
Questions:
A) Is normal that memory will increase? If client mode need 500M then 1G for
server mode is not enought? Should I increase the heap? How much?
B) Is a know problem? Is server option for windows not good supported?
I have double checked the problem. If I return to the client mode then the
tomcat will run without problem (excluding some software change problems)
No use of native code (JNI).
C) How to track better what happens in server mode? If there is a bug or is normal?
Please help me. Thanks in advance.

this problem may arise if u r using a windows 95 series of OS. after starting the dos window, go to that windows properties and increase the memory allocations to maximum, dont let it be at auto. I think this should help u

SQL Server 2012- Memory Leak Issue

Team,
We are running a Mission Critical Application on SQL Server 2012 SP2(11.0.5058) which is configured on Always ON Synchronous mode. Offlate due to heavy development work, Application team have come up with stating memory issues. I have analysed all the areas
and everything looks normal. Please suggest if we have to patch the latest CU4 for SQL Server 2012 SP2.
The checks were performed on the below areas:
- Errorlog, System Logs - No errors reported.
- There are close to 8 Databases hosted on the instances which are all configured for AlwaysON. SQL Server is running on VM Infrastructure and the total physical memory allocated is 96GB out of which SQL is capped for 92GB.
-The Page Life Expectancy is healthy and is showing a greater number. There are no Signal waits either or pending memory grants.
- The writes are more than reads for one of the databases which is flagged with application team. There are no blockings & Deadlocks.
Please suggest me the future course of action and your inputs are much appreciated.
Best Regards,
Sharath

Actual issue is- Application team have reported a memory leak and their builds have significantly slowed down. They suspect that its Database memory leak. However I have verified from database end and gave the above inputs.
The AOAGs are good. I was looking for any pointers whether there are any bugs which is related to memory leaks in SQL Server 2012. I know all of them are addressed with SQL Server 2012 SP2.
Application team has NO idea about SQL Server do they ? And to say SQL Server has memory leak you have to actually prove it did they showed any proof. Its common for application team to say SQL Server is leaking memory because they are unaware about fact
by default SQL Server would take as much memory as possible and would release when SQLOS asks it to do so. This might give sign that it is leaking memory BUT IT IS NOT.
As you already said AOAG is working fine so I am presuming there is nothing much to worry. To monitor memory usage in SQL Server 2012 you can use below counters
SQL Server: Memory Manager-- Target Server Memory (KB)
SQL Server: Memory Manager--Total Server Memory (KB)
SQL Server: Memory Manager- Free Memory (KB)
SQL Server: Memory Manager--Database Cache Memory (KB)

Problem with PermGen memory (Java) - Tomcat Server - Business Object XI

We have installed Business Objects XI on a W2003 Standard with SP2 (x86), using Tomcat as web server and MySQL as DBMS. The server has 4 GB of RAM and dual-core processor. From the beginning we have been given the memory problems of the Java virtual machine. The exception that occurs is of type "java.lang.OutOfMemoryError: PermGen space failure". We modify environment variables (JAVA_OPTS) -XX: PermSize = 256m and-XX: MaxPermSize = 512m and install the monitor LambdaProbe to see the use made of memory. We note that at no time was the PermGen memory indicated by these variables, continuing in that has a default 64MB. For this reason we decided to change the Tomcat 5.5 BO included in the version 6.0.20 and also updated Java to version 1.6.0_18-b07, and make deployment by wdeploy.bat file that comes with BusinessObjects (changing config.tomcat55 and tomcat55.xml). The deployment was successful and everything works, but as with the previous version of Java / Tomcat, shortly PermGen memory fills and returns to "hang". In this latest version of Tomcat installed as a service, do not use environment variables, use an application, "Configure Tomcat", which is a tab to pass parameters to the JVM. After looking at many sites, I have seen to be putting "-D" to pass the parameter. Currently this is my configuration:
-Dcatalina.home = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0-Dcatalina.base = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0-Djava.endorsed.dirs = C : \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ endorsed-Djava.io.tmpdir = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ temp-Djava.util.logging.manager = org.apache.juli . ClassLoaderLogManager-Djava.util.logging.config.file = C: \ Program Files \ Apache Software Foundation \ Tomcat 6.0 \ conf \ logging.properties-Dcom.sun.management.jmxremote-D-Xms2g-D-Xmx2g-D -XX: + UseConcMarkSweepGC-D-XX:-D PermSize = 256m-XX: MaxPermSize = 512m-Daf.configdir = C: / Program Files / Business Objects / Dashboard and Analytics 12.0-D-verbose: gc-D-XX : + PrintGCTimeStamps-D-XX: + PrintGCDetails
I tried changing the values of-XX: PermSize and XX: MaxPermSize, and modifying the various policies of the Garbage Collector (-XX: + UseConcMarkSweepGC,-XX: + UseParNewGC,-XX: + UseParallelGC, ...), but nothing. Any idea how to get change the value of the report? Or how to solve this problem?
Thank you!

Victor,
Is the Product you are using BusinessObjects Enterprise XI (Release 1)?
With XIR2 and XI31, Tomcat 5.0 and Tomcat 5.5 are included with the software, and when installed with the BOE installer, you will get an application installed to the startmenu named "Tomcat Configuration".
Using this "Tomcat Configuration" utility, there are several configuration options available. On the JAVA tab, you will see the JAVA_OPTS that are set (These are prefixed with "-D") and also your initial and max memory sizes are listed at the bottom (Max 1024 by default in XI31).
Here is the default setting for permsize in XI31 Tomcat:
-XX:MaxPermSize=256M
From your post, your issue might be the spaces in between your values (there should be no spaces, each "-" parameter on its own line).
I would suggest starting Tomcat and reviewing your stdout.log file to review what options were set.
Hope that helps

XSLTC not working in -server mode of JVM

I am translating one of my request xml to response xml using SinglePropertyAvailabilityRQ.xsl. I am using XSLTC technique of transformation. This works perfectly when I am running it normal JVM mode.

How to start Jrockit as server mode using Tomcat jsvc (chroot)

Hi,
I was reading the product documentation and came across Jrockit defaulting as server mode? In the log file however, during startup there is no info on the VM mode - is there a way to get Jrockit VM to show? java -version does not output server mode either :-(.
Currently testing Jrockit and may possibly move over from Sun :-).
Thanks in advance!

Thanks Henrik for explaining!
After installing Jrockit 5.0_04 on one of our test machines, we keep getting random illegal memory access errors during stress testing:

UnmarshalException while using prop java.rmi.server.ignoreStubClasses=true

I have created a test program to check the behaviour of setting the java.rmi.server.ignoreStubClasses property to true on the server side and not setting this flag on the client side.
This requirement is due to updation of an already running system, with stubs to a new version without stubs, without shutting down the system.
The files used by me are given below.
File Hello.java
package example.hello;
import java.rmi.Remote;
import java.rmi.RemoteException;
public interface Hello extends Remote {
String sayHello() throws RemoteException;
File Server.java
package example.hello;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
import java.rmi.server.UnicastRemoteObject;
public class Server implements Hello {
public Server() {}
public String sayHello() {
return "Hello, world!";
public static void main(String args[]) {
try {
LocateRegistry.createRegistry(1099);
Server obj = new Server();
Hello stub = (Hello) UnicastRemoteObject.exportObject(obj, 0);
// Bind the remote object's stub in the registry
Registry registry = LocateRegistry.getRegistry();
registry.bind("Hello", stub);
System.err.println("Server ready");
catch (Exception e)
System.err.println("Server exception: " + e.toString());
e.printStackTrace();
File Client.java
package example.hello;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class Client {
private Client() {}
public static void main(String[] args) {
String host = (args.length < 1) ? null : args[0];
try {
Registry registry = LocateRegistry.getRegistry(host);
Hello stub = (Hello) registry.lookup("Hello");
String response = stub.sayHello();
System.out.println("response: " + response);
} catch (Exception e) {
System.err.println("Client exception: " + e.toString());
e.printStackTrace();
First I run file Server.java using the following script (server.bat)
java -Djava.rmi.server.ignoreStubClasses=true -classpath .; example.hello.Server
pause
Then the client is run using the following script (client.bat)
java -classpath .; example.hello.Client 132.186.96.210
pause
While running the client, the following exception is obtained.
Client exception: java.rmi.ServerException: RemoteException occurred in server thread; nested except

... 6 more
I am not able to figure out why this thing is happening, If i also set the property java.rmi.server.ignoreStubClasses=true on the client side everything goes fine. But this I can't do. I can't set the property on the client side as the system is up and already running.
I am using JDK version 1.5.0_06. Same exception comes under JDK 6.0
Any help will be highly appreciated.

I think this is a bug. When you exported the Registry from your server JVM it was also exported with java.rmi.server.ignoreStubClasses=true, but the Registry bootstrap at the client requires the 1.1 stub protocol for compatiblity reasons so you got this error. I would report this on the Bug Parade.
You could get around it by setting java.rmi.server.ignoreStubClasses after exporting the Registry.
BTW java.rmi.server.ignoreStubClasses isn't supposed to do anything at the client whether true or false so you can cut your testing space in half.

Jco Connection works on Single server mode, but not over network?

Hello,
Error - com.sap.dictionary.runtime.DdException: 'XXXXXX' not properly defined! Unable to create Metadata connection for Dictionary Provider. Either the logical System Name 'XXXXXX' has not been properly defined in the System Landscape Directory, or you are not using a MsgServerDestination (AppServerDestinations are not permitted for Metadata connections
This is the error at one of the remote machines. The JCo Connection works on the J2EE host system (while testing and pinging under the Single Server mode.)
I believe this error will be rectified if I upgrade to SPS7, but we have certain other considerations that restrict us from doing that.
Could someone please point out the exact location thats responsible for this if possible and maybe I could just upgrade that part and clear this?
Thanks

Hi,
you should consider three things if your java instance is on network.
1. SLD ( check if java instance is listed on SLD and test the connection from portal to SLD.
2. You need an entry in the services files of both the Java and ABAP servers as such:
sapms<SID> 3600/tcp
Remember to always have a blank line at the bottom of the services file!
3. try to add the certificate in portal.
if you can provide with the exact error message it would be easy to help.
Kind regards,
vamsi.

Sun Java Application Server 9

Hi,
I noticed that Sun Java Application Server 9 has a platform edition available.
(In the Application Server section of the site it appears that latest version with an enterprise release is version 8.1.)
Does anyone know if an enterprise edition is available for version 9? If not yet available, is there a timeline for an enterprise release?

The Platform edition is intended to be run as a single JVM and lacks high availability and cluster
support. The Enterprise edition has full support for clustering, high availabiilty, fail-over, and
load-balancing. You can try out these features by using our Glassfish V2 release.
9 PE would not be supported as an upgrade within any Java Enterprise System release,
since a PE release does not contain all the features of an EE release. Once SJS AS 9 EE
is released it will be included in a future rev of the Java Enterprise System.

Sun Java Web Server 6.1SP4 deadlock, stops responding

Hi, i have a java web app on a Java Web SErver 6.1SP4 and when there are a lot of users the web server hangs, it stops responing. After a while (from 2 to 15 minutes) it start responding again. This serves neither dinamic nor static content. CPU usage is 100%. Just stoping and restarting the web server instance it works properly (even with the same or greater number of clients).
Reading many posts some one wrote to use pstack to see whats happening. I did it, but i can't interpret results (i think there is a deadlock but don't know if thats true and how to resolve it).
Any hint will be appreciated

hi
sorry for the delayed response.
well, the problem that you are trying to run into is very common when your server is getting good amount of load and uses large amount of servlet/jsp web applications running.
here is a url that you might find it a useful read
http://java.sun.com/docs/hotspot/gc1.4.2/index.html#4.%20Types%20of%20Collectors|outline
if you do not want to take this trouble reading this document and want a quick solution, you do can do couple of things:
- first understand how to size the heap
http://java.sun.com/docs/hotspot/gc1.4.2/index.html#3.%20Sizing%20the%20Generations|outline
- understand that the system is paused because jvm is busy doing garbage collection before allowing the web server to continue.
- this can be avoided by properly tuning the jvm to how you think the server should behave. unfortunately, there is no miracle one one line to fix this issue
- by careful and decent analysis of your system, you can tune your jvm properly that it can scale very well without any glitches.
though, you will need to take the pain to learn the garbage collection acronyms and see what's best suited for you.
- first, you want to know what is happening inside the jvm before you proceed to optimize . you can do this by adding this option
-verbose:gc -XX:+PrintGCDetails
How to add this option in the server.xml , is by doing something like
start admin server -> manager your server -> click Java tab
-> click on JVM Option in the left side
-> Add this JVM option -verbose:gc -XX:+PrintGCDetails
-> restart the server
-> note, you do NOT want to leave the above option in the production environment as this will tremendously slow your application and this is meant to be only for development purposes.
- if your server is a multi processor server (has more than 1 CPU) and you want less pause time, you can typically try adding this jvm option to your server and restarting it.
-XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled
here are few other short cut , jvm options that you also try in your devleopment environment before going to production.
Server application(Like Web Server 6.1) running alone on a large multi-processor server with 4gb of physical memory.
#java -server -XX:+AggressiveHeap
Two applications running on a large multi-processor server with 4gb of physical memory. Each java application instance is allocated a part of total system memory by an explicit specification of the maximum and minimum heap sizes.
#java -server -XX:+AggressiveHeap -Xms1024m -Xmx1024m
(again, do your research before you use this option in the production environment)

DHCP Server is not passing out DHCP Leases

I can't seem to figure out why DHCP server is not passing out DHCP lease a client?
Also I can't seem to figure out why NVI0 interface is UP? I have setup another box similarly and NVI0 is down on that and the DHCP server is working fine on that too. Strange!
I am working on CISCO 881 VPN Router...Please have a look at it and let me know. Thanks
Here is the configuration in the box...

Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.
It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you
want to use.

Hi Jennifer,
I have gotten it resolved. Per your suggestion, I have turned on debug ip dhcp events and found that POOL EMPTY message. After little research, I found out that I have made a mistake in my excluded-address range.
I have had it as
ip dhcp excluded-address 192.168.1.1 192.168.100.101
It should have been
ip dhcp excluded-address 192.168.1.1 192.168.1.101.
It was a typo.
Thank you for the suggestion.

Java Connector Server - run as service on Windows

Hi
For whatever reason, I'm not able to install the java Connector Server as a service on my Windows server.
It does give a successful message upon connectorserver.bat /install, but it does not show up.
I can run and use it fine with the command connectorserver.bat /run
Also, the .Net version installs fine as a service.
Any ideas out there?
- Lars

Update in this one.
I got it installed as a service (it was a user rights problem). Now the problem is that it won't start.
It gives me the error:
+[173 javajni.c] [error] %1 is not a valid Win32 application.+
+[898 prunsrv.c] [error] Failed creating java c:\Oracle\Java\jdk1.7.0_10\jre\bin\server\jvm.dll+
+[1132 prunsrv.c] [error] ServiceStart returned 1+
In dire need of help, as it would be impossible to keep running this connectorserver with the /run parameter. :)
Some additional information:
OS: MS Win Server 2008 R2
System: 64-bit
Java-version: JDK1.7.0_10

MBean classloading in Sun Java Application Server 9.0

Hi,
I am having a classloading issue when attempting to register my custom MBeans within the Sun Java Application Server 9.0 environment.
The instructions say I can put either my classes or a Jar archive in domain_dir/applications/mbeans. When I put just the class files there it works fine. However, when I attempt to Jar those same class files (properly I might add) and put that Jar there it fails to find the mbean classes.
Does anyone know anything about this?
Thanks for any help.

Hi Kedar,
Thanks for the reply. Yes, I finally figured it out.
The custom MBeans seem to work well for the most part though I don't know for sure if I'm using them in the way they were really intended.
Basically, I want to run 'services' on my application server for the lifetime of the server. I want these 'services' to maintain things like runtime caching of information over time that is not persisted in a DB but needs to be kept around in active memory to be used at a later time, but only while the application server is up and running.
Another thing I would like to do is have them receive JMS notifications directly, but I seem to be having trouble when subscribing as a consumer within my custom MBean. The topic thread on that is here:
http://forum.java.sun.com/thread.jspa?threadID=5153124&tstart=0

Hi Dqzz,
According to your description, you encounter the "Unable to establish server mode" error. Right?
In Analysis Services, this issue has been reported and it has been fixed in the later services pack. Please see: SSMS
raises "Unable to establish server mode" error if SSAS encounters errors during startup. However, it also can be related to running out of memory issue which will cause this error. Please refer to a blog below:
https://cwebbbi.wordpress.com/2012/05/28/unable-to-establish-server-mode-error-in-ssms/
If you have any question, please feel free to ask.
