[PTLsim-devel] ptlstats: Cannot get snapshot 'final'

Fri Aug 10 18:59:26 EDT 2007

Thanks for the quick response.

It turns out that the simulation has been crashing due to log file being 
too large. It's not liking 2GB+ log file. I reduced the loglevel to reduce 
the size of the log file, and the simulation runs to completion now.
