Lately I’ve been seeing a lot of instability and memory issues in Eclipse (Europa) with WTP, both in my own use, from co-workers, and on IRC. Today, a friend sent me this link which appears to show the cause for at least some of these issues. It appears the latest release used:

–launcher.XXMaxPermSize256m

in the eclipse.ini to try to set the permgen size to 256 mb (which is what is usually needed for a wtp setup). This doesn’t work, and as a result, a lot of memory issues occur. It looks as though they’ll be releasing a fix soon, but until then, taking that line out and adding this:

-XX:MaxPermSize=256m

in the eclipse.ini file (after the -vmargs) should fix it.
