Hi there, I was recently asked about this and decided to clobber this mailing list for I'm having good success now. Mac OS X 10.5.6 Java 1.5.0_16 Eclipse 3.4.0 Pydev Extension 1.4.2 I did modify the memory foot print to 800m; see below. I wanted to set it higher but Mac OS X Java didn't support setting it to even 900m. When Pydev Extension does the code analysis it really takes a lot of memory and when I had it set to 500m it would run out. Note that most people do not touch this part for their own programs and it only needs to be done after updates. It takes like 2 minutes in the background. The result shows very few real errors in the CCPN code that it can detect. Perhaps the Cambridge team can expand on their (mis-)haps with Eclipse for us?
