ERROR:set_share_mode shmops->shm_alloc fail!

[Terry Dwyer 61 8 9491 5161]

I had a problem similar to yours that I've recently solved.  I'm running
Samba 2.0.2 under FreeBSD-2.2.8-Stable(11/03/1999) 

My error message was slightly different to yours, and only occured when
starting smbd and nmbd.  It was to the effect that IPC$ services were
unavailable and identified a call to a routine that seemed to want to
allocate SysV Shared memory. 

I recompiled a new kernel with 1MB of Shared memory (SYSV_SHM) and the
problem went away. 

Considering that every version of Samba up to the most recent I had run 
(1.9.18) was happy with 256KB of SYSV_SHM, needing to provide 1MB is a bit 
of a jump!

I hope this helps to point you in the right direction.
