Re: [Gems-users] Ruby crashing in sequencer

[Mike Marty <mikem@xxxxxxxxxxx>]

I would generate a protocol trace for address 0xd35c080 starting at around
time 144500000

To do this, enter the following commands:

ruby0.debug-output-file /tmp/debug
ruby0.debug-start-time "144500000"

Make sure RUBY_DEBUG is set to true in the Makefile and that the
PROTOCOL_DEBUG_TRACE is true in rubyconfig.defaults

Then grep /tmp/debug with "0xd35c080" to see why the request times out.
