shm error on Solaris 8
I saw a problem similar to mine on this thread: http://www.hswn.dk/hobbiton/2006/08/msg00667.html <http://www.hswn.dk/hobbiton/2006/08/msg00667.html> My situation may be a little different though. In my case I've been tasked with running a hobbit instance in parallel with an existing bb4 instance ON THE SAME HOST. I've modified my hobbitserver.cfg to run on port 1985 but I get the same error in /var/log/hobbitlaunch.log as David observed. A section of the logs follows (similar messages repeat): 2006-09-27 12:48:56 hobbitlaunch starting 2006-09-27 12:48:56 Loading tasklist configuration from /opt/home/hobbit/server/etc/hobbitlaunch.cfg 2006-09-27 12:48:56 Loading hostnames 2006-09-27 12:48:56 Loading saved state 2006-09-27 12:48:56 Cannot access checkpoint file /opt/home/hobbit/server/tmp/hobbitd.chk for restore 2006-09-27 12:48:56 Setting up network listener on 0.0.0.0:1985 2006-09-27 12:48:56 Setting up signal handlers 2006-09-27 12:48:56 Setting up hobbitd channels 2006-09-27 12:48:56 Could not attach shm Too many open files 2006-09-27 12:48:56 Cannot setup client channel 2006-09-27 12:48:56 Task hobbitd terminated, status 1
Help? I'm not comfortable tweaking kernel parameters. Can someone walk me through it? Should it solve my problems? Can hobbit and bb4 co-exist on the same host?

I've modified /etc/system to include: set shmsys:shminfo_shmseg=7
and rebooted... but I still get the exact same error. What else must be changed for Solaris 8 ?

try running "ulimit -a" and see if you are being limited as to how many open files or memory you can access. If so you can change the limit to unlimited.

Ahh, file descriptors is at it's default, 256. Does this need to be increased? I've tried doing a 'ulimit -n 1024' and confirmed the change before doing "./server/hobbit.sh start" and it hasn't changed the results.
Do I need to change something again in /etc/system to make this a permanent change ?

rlim_fd_cur

No. I don't think it could be the right way. (and this is limited to
1024...rlim_fd_max in /etc/system)
2006-09-27 12:48:56 Could not attach shm Too many open files
extract of man shmat :
EMFILE
The number of shared memory segments attached to the
calling process would exceed the system-imposed limit.I have one box with 8 segment for hobbit.
Why don't you put shmseg to 32 and try again ? set shmsys:shminfo_shmseg=32 (I'd even set it to 64)
and also increase shminfo_shmmni set shmsys:shminfo_shmmni=512

sysdef -i | grep SHM

wow
put that :
