--- Comment #4 from Mark Thomas <ma...@apache.org> ---
The crash log indicates that the crash occurred in the Poller.

I've reviewed the changes since Tomcat 7.0.91 and Tomcat Native 1.2.17 and I
don't see any references in the change log for fixing issues that could trigger
a crash like this.

There is a significant change in 7.0.99 onwards where the code was refactored
to use a single pollset rather than multiple.

I have also compared the 7.0.x code to 8.5.x and while a direct comparison is
not possible due to 7.0.x having to support Comet, I don't see any obvious
differences that could trigger a crash. I did make a few cosmetic changes to
bring 7.0.x into line with 8.5.x and I also fixed one threading issue although
the 8.5.x changelog indicated that that was related to timeouts.

At this point I suspect a bug in the code that handled multiple pollsets. I am
therefore going to resolve this as fixed. If you still see this issue, or one
like it please:
- update to the latest available major Tomact version (7.0.x, 8.5.x, 9.0.x ot
10.0.x) and latest available Tomcat native version
- retest

Anything you can do to narrow down how to trigger the issue is helpful and
steps that reproduce are ideal.
