On HP-UX systems a large number of SYSV shared memory segments cause performance degradations. In R5.0.8, the default segment size has been increased to improve system performance. The default size was 12 megabytes and is now set to the value of the kernel shmmax (up to 256 megabytes). This will increase the initial swap space used by the new default value. If this is an issue the old default size can be configured by setting the shell variable Notes_SHARED_DPOOLSIZE = 12000000.
