Memory issues on large sites.

I’ve used auditmypc for sometime with great success. The last few months as my sites have grown I have had several issues. Running out of memory, program stopping with large amount of queued url’s. I have tried both IE and Mozilla. Same issues.

Java memory has been increased to -Xmx1028m on one of my pc’s. On other PC’s if I increase from -Xmx128m to -Xmx256m I get an error that says the java environment can’t be started.

I am using XP pro SP 2. This occurs on 5 different pc’s.

Any help to generate large (20,000 – 30000+ urls) would be appreciated.
