Looking into the article I mentioned below in further detail, a lot of the users recommend actually doubling (200% instead of 40%) the heap size, so you might want to try that if the 40% increase does not work, and assuming you have the memory to do so.

I'd check it out. The rough solution to the problem seems to be increasing your heap size by approx 40%: "Remember that 512 MB is 512 MB of space whether it's 32 bit or 64 bit. On 64-bit, Java references (pointers) are twice as large. So pointer-rich objects would be larger, and your memory footprint would be larger. A rough rule of thumb we have found useful over a small universe of Java applications is that a 40% increase in heap size usually suffices to deal with this object size dilation. In other words, -Xmx512M in 32-bit becomes roughly -Xmx720M for 64-bit and so on." Hopefully this will sort you out! As always though, also try grabbing the latest JDK (1.5_08) to see if it makes any difference in the x64 machine. -----Original Message----- From: lfleal [mailto:[EMAIL PROTECTED] Sent: 25 August 2006 12:36 To: user@ant.apache.org Subject: RE: OutOfMemoryError when building on x64 David, The same build script works just fine under 1.5 on a win 32 server, the only difference is that on the new server, the x64 version of the 1.5 JDK is used. The ant options are set to a max heap of 512m (where the old server uses the default). There seems to be more going on here...
