Re: Error -25588 and errno 22 from shmat()

Here's what I've got the values raised to: set semsys:seminfo_semmni = 2048 set semsys:seminfo_semmns = 2048 set semsys:seminfo_semmnu = 2048 set semsys:seminfo_semmsl = 25 set semsys:seminfo_semmap = 2048 set shmsys:shminfo_shmmax = 671088640 set shmsys:shminfo_shmseg = 64 I had gone a bit higher, but to no avail. Any ideas?
