Hello, I am relatively new to the forum, so I am not familiar with all the procedures and etiquite but here goes my first post. I am running a P4 2.6GHz w 1.5GHz ram. LW Pro 4.9.11 and Java 1.4.2_05 . LW was generating errors like crazy and then choking system to where I had to ctrl-alt-del kill LW regularly. I read the posts, tried the recomendations, and got LW to run for about an hour without restart. I then tried turning off HyperThreading and LW ran for about 4 hours with a full queue and a couple of thousand files shared. I was running as Ultrapeer on DSL the whole time. A few more tweaks and I might be there. Anyone have any new input on this problem or how to increase the heap in Java?
