that I had run the system stably on identical hardware for some time.
For those following this other than Pete, who I've been in private
correspondence with: it seems that he is running into two different
deadlocks in the routing code. One of them (at least) is triggered by a
lock order problem relating to the processing of ICMP redirects -- uncommon
in most configurations, but quite a few on his network, which triggers
quickly under load. Kip Macy has corrected at least one (both?) problems
in head, and plans to MFC the fixes in the near future. We'll follow up
further once the fixes are merged, and if any further problems transpire.
Do you have any other details about these issues ? Were the fixes ever MFC'd
Hi Mike, et al,
I gave Kip a ping about MFCing the fixes and he said he would do that, but has
apparently been preoccupied. I'm working on an MFC patch currently, but as
I'm not all that familiar with the routing code, and the bug fixes were mixed
with feature enhancements in his original commits, it will probably take me a
bit longer to produce a candidate patch.
