Hi Mark,

The Gump failures we are seeing are due to the tests taking more than an
hour to run. I've looked through the logs and I don't see any obvious
culprits although a second pair of eyes wouldn't hurt.
I've made a few changes to the test configuration to try and speed
things up (Gump is generally slow and anything I/O related is very slow)
but early indications are that they won't help.
Suggestions welcome.
I had a look at the last failure today:
http://vmgump.apache.org/gump/public/tomcat-8.0.x/tomcat-tc8.0.x-test-nio2/gump_work/build_tomcat-8.0.x_tomcat-tc8.0.x-test-nio2.html
When adding the "elapsed" times of the tests run I get 3155 seconds, so
there are 445 seconds which are not accounted by "elapsed". It seems
those are neither in front of the test run (compile, validate) nor is it
the last aborted test. Probably just 1-2 seconds per test which is not
accounted by "elapsed".
I compared the elapsed times of the individual tests with the ones on my
local (slow) Solaris machine where it takes about 40 minutes to run all
tests for one connector. Here's a comparison showing the delta between
the elapsed times, the slow down in percent, the absolute times for gump
and my system and the test name. The list is sorted by biggest delta
first. I only show the tests that need at least 10 seconds more on Gump
than here on my system:

Maybe the list gives an idea, whether it is more an I/O or CPU shortage
or something else?
