Thanks Pavel, although actually the command is: # ipcs -u
# ipcs -m
is not very useful - just produces a lot of spam with no totals.
# ipcs -u
# ipcs -l
showed up the problem.

What about to increase shmmax in the system when it complains that cannot
get allocated new 262kB?
You can check what is your size: # sysctl -a|grep shmmax
This cmd says you what is already used: # ipcs -m
You can increase it in /etc/sysctl (just put there something big, it is just
a restriction, kernel.shmmax = XXXX)  and then apply it by : # sysctl -p

I uninstalled hobbit-4.2.0-7.el5.re.i386.rpm and compiled hobbit-4.2.0 from
source with the allinone.patch and get exactly the same error.
It might be worth noting that this was originally a minimum CentOS 5 install
- I had to install gcc-c++ (and rrd-devel and pcre-devel) to compile hobbit,
and I previously had to install gcc for compiling some other software - all
from yum.
The server has 2 GB of RAM but is running several other services.
Any other ideas?

Just compile it from source.  If you don't know how to do that I can give
you instructions command by command, just ask.  I use CentOS5 on my boxes
but I've never bothered with the RPM.

I installed an RPM of hobbit-4.2.0 called hobbit-4.2.0-7.el5.re.i386.rpm,
which I probably got from here: 
It includes the All-in-one patch.  So I configured the cfg files and started
hobbit, but I get this in hobbitlaunch.log:

2007-11-29 17:33:47 Task hobbitd terminated, status 1 

This is the first time I've started it, so I presume that this is normal:
"Cannot access checkpoint file /usr/libexec/hobbit/server/tmp/hobbitd.chk
for restore".  The problem looks like this:  "Could not get shm of size
262144: No space left on device".  I see that there are two similar issues
listed on  <http://www.hswn.dk/hobbit/help/known-issues.html>
http://www.hswn.dk/hobbit/help/known-issues.html that relate to FreeBSD, but
none of the sysctl keys listed are in this version of Linux:

# cat /proc/version 
Linux version 2.6.18-8.1.15.el5.centos.plus (mockbuild at builder6.centos.org
<mailto:mockbuild at builder6.centos.org> ) (gcc version 4.1.1 20070105 (Red
Hat 4.1.1-52)) #1 SMP Thu Oct 25 06:49:40 EDT 2007

Google returns 1 result for "Could not get shm of size" "No space left on
device" and that was the Known Issues page I've already checked.  Any ideas?

Also, I noticed that the hobbitd.pid file did not get deleted when hobbitd
terminated.  It seems like it should have been.

Many thanks,
