Hi, Our server has been at times very slow lately and unresponsive and needed to be restarted several times. I found the following error in the logs about perl: Nov 15 21:02:49 kernel: Mem-info: Nov 15 21:02:49 kernel: Zone:DMA freepages: 1055 min: 1056 low: 1088 high: 1120 Nov 15 21:02:49 kernel: Zone:Normal freepages: 765 min: 766 low: 4031 high: 5791 Nov 15 21:02:49 kernel: Zone:HighMem freepages: 264 min: 255 low: 510 high: 765 Nov 15 21:02:49 kernel: Free pages: 2084 ( 264 HighMem) Nov 15 21:02:49 kernel: ( Active: 247285/3347, inactive_laundry: 0, inactive_clean: 0, free: 2084 ) Nov 15 21:02:49 kernel: aa:2127 ac:20 id:0 il:0 ic:0 fr:1055 Nov 15 21:02:49 kernel: aa:212147 ac:2140 id:3347 il:0 ic:0 fr:765 Nov 15 21:02:49 kernel: aa:30593 ac:258 id:0 il:0 ic:0 fr:264 Nov 15 21:02:49 kernel: 1*4kB 1*8kB 1*16kB 1*32kB 1*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 1*4096kB = 4220kB) Nov 15 21:02:49 kernel: 3*4kB 1*8kB 2*16kB 0*32kB 1*64kB 1*128kB 1*256kB 1*512kB 0*1024kB 1*2048kB 0*4096kB = 3060kB) Nov 15 21:02:49 kernel: 0*4kB 6*8kB 1*16kB 1*32kB 1*64kB 3*128kB 0*256kB 1*512kB 0*1024kB 0*2048kB 0*4096kB = 1056kB) Nov 15 21:02:49 kernel: Swap cache: add 594668, delete 591932, find 209410/234040, race 0+108 Nov 15 21:02:52 kernel: 1492 pages of slabcache Nov 15 21:02:55 kernel: 228 pages of kernel stacks Nov 15 21:02:57 kernel: 0 lowmem pagetables, 1117 highmem pagetables Nov 15 21:02:58 kernel: Free swap: 0kB Nov 15 21:02:59 kernel: 262138 pages of RAM Nov 15 21:02:59 kernel: 32762 pages of HIGHMEM Nov 15 21:03:00 kernel: 4485 reserved pages Nov 15 21:03:00 kernel: 7236 pages shared Nov 15 21:03:01 kernel: 2736 pages swap cached Nov 15 21:03:01 kernel: Out of Memory: Killed process 9732 (perl).
