I have a system that connects different jails via bridges and epair's. This
allows me to simulate multiple routers at one time so that routing protocols
can be tested. Each test builds and tears down it's unique topology.
Typically multiple of these tests are run at the same time. When these series
of tests are run, before completion of the entire test suite we have the kernel
crash. I'm porting the infrastructure and test suites from linux so I don't
have a huge history with these tests on FreeBSD, but I have seen this crash 4
times in a row. Looks like I can make this happen at will. If you have things
you would like me to do feel free to reach out and I'll get the data.
