I am seeing out of memory issues on a domU running OpenNMS, which is java based, with tomcat4 interface and postgresql back end. Postgres depends on the OS to handle most if the memory caching AFAIK. domU - 710 megs, using 1 disk partition for "/" and 1 for "swap" Centos 4.1 postgresql-server-7.4.8-1.RHEL4.1 Postgres error Free pages: 3740kB (0kB HighMem) Active:92154 inactive:79697 dirty:0 writeback:0 unstable:0 free:935 slab:1709 mapped:167286 pagetables:756 DMA free:3740kB min:3396kB low:4244kB high:5092kB active:368616kB inactive:318788kB present:720896kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 Normal free:0kB min:0kB low:0kB high:0kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 HighMem free:0kB min:128kB low:160kB high:192kB active:0kB inactive:0kB present:0kB pages_scanned:0 all_unreclaimable? no lowmem_reserve[]: 0 0 0 DMA: 13*4kB 35*8kB 7*16kB 1*32kB 1*64kB 1*128kB 0*256kB 0*512kB 1*1024kB 1*2048kB 0*4096kB = 3740kB Normal: empty HighMem: empty Swap cache: add 331852, delete 331838, find 38182/43573, race 0+10 Free swap = 0kB Total swap = 1124508kB Out of Memory: Killed process 5051 (postmaster).
