[-- Attachment #1 --] 5.1 by default it appears has kern.ipc.shmmax: 33554432 you can either increase this sysctl or you can try to decrease the total memory for sybase. for ASE 12.5, you can probably just lower "max memory" in your configuration file. for 12.0, "total memory" would be the one to lower. I am not sure if sybase will let you allocate less shared memory than the default, though. i would check the shared memory and semaphore requirements of ASE and try to modify the equivalent sysctls for your system. i am not positive, but i think any changes made to these sysctls will need to be put into /boot/loader.conf to be read at boot time. -Anthony.
