That it is still present in the release notes is either an oversight or a recognition of the fact that the port is still done on Solaris 2.4. The parameter stands for 'enable shared memory workaround'. The problem is definitively fixed in 2.6 and I believe it is fully fixed in 2.5 and 2.5.1 regardless of whether you include enable_sm_wa in the /etc/system file. Removing it on your Solaris 2.6 platform will not break anything and removes an unnecessary warning. > Also check that the ...shmmin=100 value is changed to ...shmmin=1. > powerd allocates a shared memory segment of 28 bytes (I truss'ed it!) > and fails if the min is set to 100! Now that is a useful tidbit which I hadn't known about.
