An internal error occurred during: "Updating indexes".Java heap space?

It was running fine half an hour before.I restarted the eclipse and getting this error now? i have 8 gb ram,window 7 64 bit OS. i have tried restarting my system but nothing helped?

-startup

-Xmx1024m

Not sure what i is the issue?

Answer 1

Old question, but I got this issue and adding more memory did not solve, so I rebuilt the java index by applying this comment from eclipse bug tracker:

I Quote:

Click in "Quick Access", Type "Rebuild Java Index" (Actually just start typing it, use the auto completion), Hit enter.

Answer 2

This may not be directly related to the question, but this fixed the java heap issues I had:

Launch eclipse using eclipse -vmargs -Xmx2048m.

From the readme included with the eclipse install:

By default, Eclipse will allocate up to 512 megabytes of Java heap memory. This should be ample for all typical development tasks. However, depending on the JRE that you are running, the number of additional plug-ins you are using, and the number of files you will be working with, you could conceivably have to increase this amount. Eclipse allows you to pass arguments directly to the Java VM using the -vmargs command line argument, which must follow all other Eclipse specific arguments. Thus, to increase the available heap memory, you would typically use:

eclipse -vmargs -Xmx<memory size>

with the value set to greater than "512M" (512 megabytes -- the default).

Answer 3

Assuming this is a heap space problem, try this FAQ: Eclipse-Wiki: FAQ How do I increase the heap size available to Eclipse?

Answer 4

If you are using eclipse or myeclipse, you can increase memory by making changes in .ini file (myeclipse.ini)

-Xmx2048m

-XX:MaxPermSize=1024m

-XX:ReservedCodeCacheSize=512m

-Dosgi.nls.warnings=ignore

It will solve problem connected with heap space.

Answer 5

If you have m2e or other Maven plugin installed, you should check if the option at 'Window -> Preferences -> Maven -> Download repository updates index on startup' is enabled. Disable it and see if it resolves out of memory issue.
