I had a similar problem with an almost identical setup to yours which turned out to be bad memory. An extra 1GB stick was added which had a bad section in the top of the memory map. This memory only got used when things got busy so everyone suspected some threading issue. We got lucky and spotted something totally absurd in the logs which prompted a memtest86 run and hey presto we got our answer.
