I have this problem on Solaris 2.5 while installing Oracle 7.3.3 but it does not seem to be related to semaphores.

To understand the problem I 'truss-ed' SVRMGR; at a certain point a process
forked by SVRMGR does the following

1. shmget(265294151, 4517888, 0640|IPC_CREAT|IPC_EXCL) = 300
2. shmat(300, 0x80000000, 040000) Err#22 EINVAL
3. shmat(300, 0x80000000, 0) Err#22 EINVAL

tstshm -b2147483648 fails in a similar way.

Any suggestions?

Thanks
