I have just installed version 4.0.4 for the first time. I'm running FreeBSD 5.3 on Intel.
When I startup Hobbit I don't get the html pages, just a few directories. I'm really without any clue right now, so I hope someone out here can help me on this one.
Looking at de logfile gives: 2005-05-29 20:25:14 Task hobbitd started with PID 43892 2005-05-29 20:25:14 Loading hostnames 2005-05-29 20:25:14 Loading saved state 2005-05-29 20:25:14 Cannot access checkpoint file /usr/local/bb/server/tmp/hobbitd.chk for restore 2005-05-29 20:25:14 Setting up network listener on 0.0.0.0:1984 2005-05-29 20:25:14 Setting up signal handlers 2005-05-29 20:25:14 Setting up hobbitd channels 2005-05-29 20:25:14 Could not get sem: No space left on device 2005-05-29 20:25:14 Cannot setup status channel 2005-05-29 20:25:14 Task hobbitd terminated, status 1
ps -aux |grep hobbit gives: hobbit 43877 0.0 0.2 1284 812 ?? Ss 8:24PM 0:00.03 /usr/local/bb/server/bin/hobbitlaunch --config=/usr/loc So I'm missing a whole bunch of processes.
And last but not least because of the logfile I checked my filesystem: df -h: Filesystem Size Used Avail Capacity Mounted on /dev/ad0s1a 248M 49M 179M 21% / devfs 1.0K 1.0K 0B 100% /dev /dev/ad0s1e 1.9G 32M 1.7G 2% /tmp /dev/ad0s1f 107G 6.3G 92G 6% /usr /dev/ad0s1d 1.9G 120M 1.7G 7% /var linprocfs 4.0K 4.0K 0B 100% /usr/compat/linux/proc devfs 1.0K 1.0K 0B 100% /usr/local/psa/named/run-root/dev
I checked the tmp dir, it is empty. I tried linking it to a directory on another slice, which gave the same effect.

That's a first - I've never seen this error before.
The problem is with one of the FreeBSD kernel parameters controlling the number of "semaphores" available on this system. Hobbit uses 6 sets of semaphores, each set contains 3 semaphores, so a total of 18 semaphores.
Try running the command "sysctl -a | grep kern.ipc.sem" to check what the kernel limits are for semaphores. The interesting values are the "kern.ipc.semmni" (the number of semaphore sets available), and "kern.ipc.semmns" (the total number of semaphores). On my FreeBSD 4.10 box, those are set at 10 and 60, respectively - and as expected Hobbit runs fine with that. But this is a global ressource, so there may be other applications on your box that use semaphores ("ipcs -s -a" as root will show you that).
I don't know enough about FreeBSD to help you with changing these parameters - Google'ing a bit for "FreeBSD+kern.ipc.semmni" indicates that this also needs tuning if you run PostgreSQL.

Thanks Henrik,
I think it's getting even more difficult looking at the following output: morpheus# sysctl -a | grep kern.ipc.sem kern.ipc.semmap: 30 kern.ipc.semmni: 10 kern.ipc.semmns: 60 kern.ipc.semmnu: 30 kern.ipc.semmsl: 60 kern.ipc.semopm: 100 kern.ipc.semume: 10 kern.ipc.semusz: 92 kern.ipc.semvmx: 32767 kern.ipc.semaem: 16384 morpheus# ipcs -s -a Semaphores: T ID KEY MODE OWNER GROUP CREATOR CGROUP NSEMS OTIME CTIME s 65536 5432001 --rw------- postgres postgres postgres postgres 17 23:21:27 23:21:27 s 65537 5432002 --rw------- postgres postgres postgres postgres 17 23:21:27 23:21:27 s 65538 5432003 --rw------- postgres postgres postgres postgres 17 23:21:27 23:21:27 s 65539 17897355 --rw------- 10010 bb 10010 bb 3 no-entry 16:31:29 s 65540 34674571 --rw------- 10010 bb 10010 bb 3 no-entry 16:31:29 s 65541 51451787 --rw------- 10010 bb 10010 bb 3 no-entry 16:31:29
I'll have a go at google with your info...

OK, so I think you're hitting the "kern.ipc.semmns" limit of 60 - that does match the output from ipcs (3x17 for postgres, 3x3 for bb - Hobbit
- gives 60. So some of the Hobbit ones are missing).
I'll have a go at google with your info...
This is the best one I've found yet. The kern.ipc.sem* sysctl settings are "read-only", so apparently they can only be modified upon a reboot, by listing them in /boot/loader.conf:

Just tried it, and adding a line with
kern.ipc.semmns="100"
to /boot/loader.conf and rebooting increases this setting. So I'd suggest taking the output from "sysctl kern.ipc.semmns", add 18 to the current value, and put that into /boot/loader.conf. Same for the kern.ipc.semmni value - increase that by 6.
That should cover what Hobbit needs.
Regards, Henrik
I've changed semmni to 20 and semmns to 100... works like a charm!
Thanks for your help Henrik!
