I am trying to run two separate projects from my tomcat server on eclipse. It will run each individually but when I try to run them both at the same time, it will not start and it prints the following on the console:
Exception in thread "main"
Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "main"
I have done some experimenting by increasing my heap by starting eclipse with :
eclipse.exe -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m
I have increased the values but still no luck. I have also tried creating a new server and I still get the same error. The interesting part is that I am working with team with the exact same code and neither member is having this problem. One member has exactly the same computer with the same ram and all specs, so I don't believe that I am truly running out of memory. Does anyone know of any other possible solutions to this problem?
-Thanks in advance
If Tomcat is running out memory, you need to give Tomcat more memory, not Eclipse. From the Run menu, open the Run Configurations and modify the VM arguments for your Tomcat launch.

In my eclipse, while running a mapreduce program, it is throwing Out of memory exception
I tryied with changing the parameters in eclipse.ini (-Xms40m
-Xmx768m values to -Xms4000m
-Xmx7680m) but still getting the same error.
What would be the solution for this.
The eclipse.ini setting only sets the heap for Eclipse itself.
For a program you run from Eclipse look at the Run Configuration for the program and set the -Xmx value in the VM arguments.
Today when i started my eclipse it gave me following error:
org.eclipse.jst.jsp.core.internal.parser.JSPSourceParser:
input could not be parsed correctly at position 150449
java.lang.StackOverflowError
Then it shows another error
An internal error occurred during:
"JSP Index Manager: Processing Resource Events".
java.lang.StackOverflowError
and then show the error and when i click on yes button it close the eclipse,
I am using eclipse indigo, can any one help please.
Most typical reason for this error is that Eclipse or its part (e.g. source code parser) ran out of memory. To increase the memory, add/change the following parameters in eclipse.ini. Depending on your machine memory, increase them 4x, even 8x:
-XX:MaxPermSize=512m -Xss2m -Xms128m -Xmx512m
You can also use these parameters as eclipse command line parameters.
See details, for example, here: Understanding memory parameters for Eclipse
If memory changes in .ini does no do the trick , best way will be to close any other applications running , after that open Task Manager , and close JAVA services running . Restart the eclipse . NOTE :- This will close the programs using Java if they are open .
Ever since I added EclipseLink to my setup I keep getting memory errors every few minutes. It really sucks because Eclipse (IDE) can't even stop resin once that happens and I have to go to the command line to kill it.
The error is usually this:
Unable to load class: java.lang.OutOfMemoryError: PermGen space
In my resin.xml I have the following hoping to correct the issue but it doesn't help:
<server-default>
<jvm-arg>-Xmx512m</jvm-arg>
<jvm-arg>-XX:MaxPermSize=1024m</jvm-arg>
<jvm-arg>-Xss1m</jvm-arg>
<jvm-arg>-XX:+CMSClassUnloadingEnabled</jvm-arg>
<jvm-arg>-XX:+CMSPermGenSweepingEnabled</jvm-arg>
</server-default>
The last two lines are the last thing I tried and it failed quickly.
Any suggestions?
Thanks.
So far a change I made has helped: I put -XX:MaxPermSize=1024m in the Eclipse server launch configuration - vm arguments.
Someone from Caucho told me that when using Eclipse the -X arguments in resin.xml are not used, so that makes sense.
So I created a Websphere Application Server in Eclipse and pointed it at my WAS_HOME and the profile I created. Whenever I try to start the server, it starts fine and according to the log I see...
[2/22/12 14:16:25:037 EST] 00000000 WsServerImpl A WSVR0001I: Server server1 open for e-business
However, Eclipse says it is still waiting to start, typically it sticks at 23%. Eventually it times out saying it couldn't start, however, the instance is still up and running fine.
How do I get it to recognize the running instance?
Your workspace folder/name could be the issue.
or for me it was the WAS installation itself. When I moved it to C:\was8 everything started to work properly. The default puts it into c:\Program Files... and that was hanging at 23%
a. Please use websphere jre to replace sun hotspot vm to launch the eclipse, like below setting in the eclipse.ini
-vm
D:/IBM/WebSphere/AppServer/java/bin/javaw.exe
b. Please make sure there is not a specail character (like 23%) in the websphere path or eclipse workpsace.
Recently, I've got the same problem with Eclipse Luna and Websphere Developer Tools... The problem was the eclipse proxy configuration
Increase the initial and max heap sizes of the VM that is loading Eclipse.
I can run Eclipse with CDT for about 15 minutes before it crashes with a java heap space out of memory error. Its always associated with the org.eclipse.cdt.internal.ui.text.CReconciler thread. It's gotten to the point where I'm running on auto pilot when it happens: "rm .lock", "y", "eclipse&" and away I go. I can't find relevant information with the Google nor have I found a similar post on SO. Anyone else run into this kind of issue before?
I'm using
Eclipse 3.6.1, Build ID: M20100909-0800
CDT 6.1
Subversion 2.2.1
Pydev 1.6.3.2
OS: Red Hat 2.16
Intel quad core machine, single monitor
I don't have root access. I don't know what other information someone might need to help diagnose this. IT person has tried to find more information but even he doesn't know what's going on. This is not strictly an issue with just my computer either.
It is possible that you need more heap space than the default Eclipse setting provides. Try launching Eclipse with 1G of heap by editing eclipse.ini and change the line starting with -Xmx to
-Xmx1024m
Alternatively you can launch from the command line with
eclipse -vmargs -Xmx1024m
[UPDATE - probably should have been suggested first ]
Tail the log file at _<workspace>_/.metadata/.log to see if there is any recurring event or error that might be leaking memory.
