OK, sorry for the delay. I have the information requested.
Please see http://people.freebsd.org/~gavin/rho-fs-hang.txt
I've started to try and narrow down where exactly the hangs started:
r208700 - June 1st - seems to work fime
r209425 - June 22st - hangs occur
If you need any more info, let me know.
Thanks,

Yes you can, by mounting a tmpfs there. fstab line: tmpfs /tmptmpfs rw 0 0 It uses swap space if neccessary. But beware: TMPFS is considered to be a highly experimental feature in FreeBSD. Well, the word "highly" is probably exaggerated, but if I remember correctly, there are still some rough edges (sendfile? double copies of its content? I'm not sure). I use it on my machines without problems.

Certainly; case in point: localhost(9.0-C)[4] uname -v FreeBSD 9.0-CURRENT #71 r210558M: Wed Jul 28 07:46:04 PDT 2010 r...@localhost:/usr/obj/usr/src/sys/CANARY localhost(9.0-C)[5] df -h /tmp FilesystemSizeUsed Avail Capacity Mounted on tmpfs 2.0G 12K2.0G 0%/tmp localhost(9.0-C)[6] > under solaris, it is automatically created under swap unless one specifically > instructs the system not to do so.. Quite so. What I do -- both in CURRENT as well as stable/7 and stable/8 -- is: localhost(9.0-C)[6] grep tmpfs /etc/fstab tmpfs /tmptmpfs rw,size=2g 0 0 localhost(9.0-C)[7] Note: doing this causes a message: WARNING: TMPFS is considered to be a highly experimental feature in FreeBSD. to be issued. That said, I've been using it quite a bit in the last couple of months, and have never had an issue with it of which I'm aware. The way I used to set up swap-backed /tmp was to have the following in /etc/rc.conf: # tmpmfs="YES" # tmpsize="2048m" # tmpmfs_flags="-i4096 -o async" (but since I'm now using tmpfs, I commented the above out in /etc/rc.conf).

Yes, this is certainly possible. Just add: tmpmfs="YES" tmpsize="32m" to /etc/rc.conf, and then either reboot, or run: /etc/rc.d/tmp start Note that this will mount a /tmp filesystem on top of anything that's already there, thus making those files inaccessible until you unmount again. (use whatever value of 32m you prefer, of course) Cheers, Matthew signature.asc Description: OpenPGP digital signature

Hmm, check_domains() in srat.c should reject the SRAT table in this case.
