I did not run Phex for the last few days, and my memory consumption still went through the roof.

Although I am finding it difficult to pinpoint exactly what task(s) is using up my memory, I did find that unmounting a very large nfs mount point returned over 300MB of RAM.

I am not an nfs expert (and I realize this is off-topic), I have been monitoring memory usage, and although all of my physical RAM is used, it never dips into virtual RAM. Therefore, I suspect that nfs is being smart by using all available free RAM to cache.

Running Phex exacerbates this RAM usage because all of my "shared" files are accessed over nfs.

Secondly, I tried running both Phex 7 and 8 with IBM's SDK v1.4.0. Phex 7 starts, but I get all kinds of NoClassDefFoundError, mostly for org/apache/crimson/tree/XmlDocument.

Phex 0.8.0.32 runs with the IBM sdk with no errors/exceptions that I noticed. Of course, it still chokes with the runaway threads.
