Hello all.
Since I'm using stable as host, and current in chroot, I'll write to
both mail list, sorry for any inconvenience.
My host is binary freebsd-updated 9;
FreeBSD 9.0-RELEASE-p3 (GENERIC) #0: Tue Jun 12 02:52:29 UTC 2012
I have chroot with latest current there installed r237089 (make
buildworld && buildkernel, no specific flags)
When I built from ports some programs in chroot all went fine, until I
got stucked process automoc (when building kdelibs4);
After few restarts I got build, and forget about it.
I'm toying now with portupgrade, and see similar stucks in ruby18 and
ruby19 (Even got few times in miniruby while building 1.8);
Here's example of stucked processes (they aren't in top, and seems
totally inactive. I haven't kill them yet, so can try to dig, but to
where?):
2677 5 Is 0:00,00 | `-- /bin/sh
2678 5 I 0:00,00 | `-- sudo su
2679 5 I 0:00,00 | `-- su
2680 5 I 0:00,01 | `-- _su (csh)
2687 5 I 0:00,03 | `-- /bin/csh -i
2690 5 I+ 0:04,34 | `-- ruby19: portupgrade: [1/237]

Is this my side's problem, or there's something wrong with current? :)
Any help appreciated.
