Subject Re: [JENKINS] Solr-trunk - Build # 1865 - Failure
Date Fri, 25 May 2012 12:01:33 GMT
I actually know what this one is now.

Jetty is shutting down, and the graceful timeout is too low, and so jetty interrupts the webapp,
and while we are waiting for merges to finish on IW#close, an interrupt is thrown and we stop
waiting. So the directory is then closed out from under the merge thread. So really, mostly
a test issue it seems?

So I changed out jetty instances in tests to a 30 second graceful shutdown. Tests went from
6 minutes for me, to 33 minutes. I won't make this fix for now :) One idea is to perhaps do
it just for this test - but even then it makes the test *much* longer, and there is no reason
it can't happen on other tests that use jetty instances. It just happens to only show up in
the test currently AFAICT.
