Message-ID: <DFrpsF.H5x@metrics.com> Date: Sun, 1 Oct 1995 11:41:03 GMT Lines: 22 Our system has 32 MB of physical memory and two swap partitions (35 MB and 50 MB). The way I figure it, this should give me 117 MB of virtual memory. And yet, with around 20 MB in use by various processes, vmstat typically reports only 6-9 MB (or less!) of virtual memory free. Further, when our web pages are getting hit heavily (at 1 MB per httpd invocation), processes (such as httpd, newsrun, trn, ...) start crashing with out of memory errors. Shouldn't the system just swap out some processes when necessary? This doesn't sound right to me, but I can't find any way of verifying how much swap space the system is using, not *how* it's using it. Can anyone enlighten me as to what's going on here? Why can't I seem to be able to allocate memory beyond 32 MB?
