It does in /dev/osm after you have configured Operating System Messages into the kernel. Same thing on the AT&T 3B2, so I suspect this is normal behaviour for all true System V Release 3 ports. I often get this notice when using huge amounts of memory, like while running gcc and X11 at the same time. Nothing seems to go wrong, though. Here's an explanation of getcpages I got from someone at AT&T: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ getcpages is the name of a function in the operating system. This function gets physically contiguous pages for a process to run. The paging daemon, vhand, is responsible for freeing up the memory as the need arises. In a busy system with limited memory and swap space and with several large processes, when the system is unable to get a contiguous page for a process the NOTICE is printed on the console. In the chapter on Performance Management of the 3B2 System Administrator's Guide there is a section on Tunable Parameters. The paging parameters in that section describe the operation of the paging daemon vhand. In the system that exhibits the problem, increase swap space and modify GPGSLO and GPGSHI as necessary. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ -- Pim Zandbergen domain : pim@cti-software.nl CTI Software BV uucp : uunet!mcsun!hp4nl!ctisbv!pim Laan Copes van Cattenburch 70 phone : +31 70 3542302 2585 GD The Hague, The Netherlands fax : +31 70 3512837
