Hello Tianrong:
It looks like you may have a simple setup issue.  As an ordinary user,
can you run ulimit -l and see if this is set high enough.  I suggest
setting this to unlimited.  Please see our userguide for more
information on this.

If this does not help there could be something else going wrong.  In
that case please reconfigure using the --enable-g=dbg option.  You can
also set the MV2_DEBUG_CORESIZE and MV2_DEBUG_SHOW_BACKTRACE options as
indicated by the following link.

Please let us know if this helps.
