[resend to get context in the bug tracker]
on the build machine I just had a de-facto system freeze where all processes would get stuck in objcache_get (^T told me). I couldn't get more information, unfortunately :/ But I could run reboot to get the machine going again, thankfully.
The box was running two and a half days, basically building non-stop. When I tried to set up another machine I tried duplicating the filesystems with cpdup over ssh and this was REAL slow, until I suspended all build processes. I don't know, maybe that has something to do with the objcache stuff? (would hint me towards mbuf or vfs). Sorry that I don't have more information.
Maybe we should find a way to make objcache_get interruptible (for instance if M_NULLOK is passed?)
