Eclipse crashes

Question

I've been having problems running eclipse. This is the exception that was thrown after the crash today. I don't understand why I can't run the standard eclipse on my Linux machine. Does anyone have any idea what the problem could be? I've tried changing the JVM a hundred times. Messed with the eclipse.ini nothing seems to work.

I'm running Eclipse 64 3.7.1 on RHEL5 AMD64;

I have tried increasing the memory int he eclipse.ini file. Here are some more errors on crash:

Here is my Eclipse.ini file:

I asked this question again here: Setting JVM maxperm size outside of Eclipse.ini and received a good answer for anyone else with this problem.

Answer 1

There may be many underlying problems responsible for your eclipse crashing with java.lang.OutOfMemoryError.

Check whether you machine is not low on memory. You can do this with the free command. Running low on memory would most likely not manifest this way, though, unless you've disabled overcommit.

Check your per process virtual memory size limits using the ulimit -v command.

Allow the JVM to grab a larger heap using the -Xmx flag.

Your eclipse may be loading a lot of plugins. Each plugin contains a number of classes and all these classes are stored in the permanent generation of the heap. Try to disable some plugins or increase permanent generation size with the -XX:MaxPermSize JVM flag.

EDIT: Now that the question has been extended with a full stack trace and exception message string, it is apparent that permanent generation size is inadequate. Thus, as suggested above, increase its size with the -XX:MaxPermSize or try to disable some plugins. Perhaps you've recently added a plugin which includes a lot of classes?

Answer 2

Going only on this log. As far as I can see this is an Memory size related issue. Have you tried taking a look at the amount of memory given too Eclipse when started? Did you perhaps configure any default JVM parameters. You might check the running Eclipse process with 'ps -aux' from the terminal after Eclipse has started.

You should see something like -Xmx512m or -XX:MaxPermSize=128m. You might also want to take a look at your eclipse.ini to see if some memory related settings is there.

Answer 3

Maybe stating the obvious but it says out of memory, is your computer running low on memory?

Try running it with vm args to allocate more memory.

eclipse -vmargs -Xmx512m
