Powerd question 1

[sstarer]

First off, thanks for any responses at all! I have a Sun Enterpise Ultra 2 clone running Solaris 5.6 with a Sybase SQL server on it. It should be running the power management daemon, but when it trys to start I get the message:
# /usr/lib/power/powerd
/usr/lib/power/powerd: shmget: Invalid argument

The shared memory parameters from sysdef are:
104857600 max shared memory segment size (SHMMAX)
200 min shared memory segment size (SHMMIN)
200 shared memory identifiers (SHMMNI)
200 max attached shm segments per process (SHMSEG)
The SQL server was configured with 100 Meg. I can't find any reference to a shared memory requirement for powerd, so if anyone out there has a suggestion, I'm, very interested in hearing from you. The reason I think powerd is an issue, is because if I lose my connection, the box shuts down to the boot prompt.

The powerd daemon makes a call to shmget() asking for a shared memory segment of 68 bytes. If you have tuned the shmsys:shminfo_shmmin parameter to a value higher than 68, you'll get this error, you need to lower shmsys:shminfo_shmmin to a value of 68 or less.

Hope this helps,
