Yes I will try to run threadscope on it, I tried it before and the event log output produced about 1.8GB, and then crashed.

Hi Tom, I'm one of the TS/ghc-events hackers and I'd like to learn more, fix it or at least put it on the TS/ghc-events issue tracker (http://trac.haskell.org/ThreadScope). Could you help me reproduce the problem? Did ThreadScope crash or RTS? Which versions? Was it 1.8GB of the log file or RAM? Did you succeed eventually? Any other TS feedback? Thank you, Mikolaj
