Hi.
I have one FreeBSD 9.1-STABLE which hangs often, and I suspect the pf.
This sure looks like on of those posts 'I did something wrong but I will
blame FreeBSD' but the thing is that I have a couple of open pr's that
concern this machine and this particular pf configuration.
So, the thing is - it hangs, and I want to narrow it down. To some panic
may be, or at least to some console message. Right now it hangs
completely and silently, I cannot even enter the kernel debugger. It
complains about nothing, I've already checked the memory with memtest86+
(two days and no errors) and installed a bunch of fresh firmwares (this
is IBM system x3560). The period between lockups decreased a lot after I
added some altq'ing, so... it may be pf or it may be not.
I will be really glad to hear some idead about how to debug the pf or
about how to narrow the cause in general.
Thanks.
Eugene.
