Hi [EMAIL PROTECTED]
As I have mentioned before my 3.9-box locks up in a strange way:
1. it is pingable
2. syn-scan gives out open ports
3. but those ports are not accessable(for ex. I can not drop in into this box
via ssh or browse port 80)
This is a second lock-up after upgrade, box stays up in max 10-12 days.
Any ideas what is going on?
Look for an app leaking (or hogging) RAM.
If OpenBSD runs out of RAM+swap, tasks asking for more memory will end
up waiting for each other to release something...which of course, none
will likely do. Result matches your description precisely (though this
is likely not the only reason such a thing can happen). It isn't a
crash, just a really nasty hang. IF you could persuade an app to stop
and release its allocated memory, the machine would roar back to life,
but almost anything you would need to do to do that takes...memory.
As I said, I'm not sure this is your problem...but it does match your
symptoms.
