Our service is running with large processes(> 4000) and a little heavy disk I/O, and the server's load is about 3.x to 4.x. But last month after I increased 2G memory to 4G, the server is always froze every two or three hours. After 5-10 minutes, it can be alive again. I have changed to RedHat kernel 2.4.18-17, and it has the same problem but a little well-- it is froze only several seconds. And the average load is above 20,higher than 2.4.18. Kernel build with 4G memory support + reiserfs + smp support + intel e100 driver module. Any advice? Thank for help. 2G + linux 2.4.18 # uptime 9:30pm up 4 days, 9:22, 7 users, load average: 3.48, 4.63, 4.63 # vmstat 2 2 procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 2 5 1 294264 20832 321096 584276 7 6 25 15 28 23 10 7 27 4 1 0 294196 13512 322424 585088 828 0 1476 540 7025 4090 18 31 51 4G + 2.4.18 freeze # uptime 3:30pm up 3:09, 5 users, load average: 534.48, 154.42, 69.21 # vmstat 2 2 procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 276 14 8 0 43788 191968 2047620 0 0 82 157 822 404 12 31 57 6 30 2 0 14704 191156 2048776 0 0 760 3564 9212 3028 21 78 1# uptime 4G + redhat 2.4.18-17 #uptime 1:25pm up 1:04, 5 users, load average: 27.79, 23.25, 20.59 # vmstat 2 2 procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 1 1 1 0 664524 277408 1585192 0 0 113 140 740 398 11 22 68 0 1 2 0 664928 277852 1585428 0 0 240 1382 4470 2194 17 43 40
