Missing /dev/null after few min

[Matthias Gamsjäger]

Hello,

I'm running freebsd for couple of years now and never had really big
problems but this one I can't solve on my own. Running releng 7 for 6 months
now but recently after running X for like 10min the systems is missing
/dev/null. So you can imaging that most programs start complaining about it.
Right now I recreate it with mknod /dev/null c 1 3 but that's not a real
solution because it starts to disappear again after few minutes.
I'm for 99% sure it's not freebsd problem but more a application problem but
I wonder if anyone ran into the same trouble after upgrading xyz port? Or
even better has a solution for it?


Regards
Matthias
