緩衝太少了

[[email protected] ~]# free -m             total       used       free     shared    buffers     cachedMem:          1152        464        687          0          8         92-/+ buffers/cache:        363        789Swap:          199        194          5

增加緩衝

$  dd if=/dev/zero of=/swapfile bs=1M count=1024 #增加1G的SWAP進去$  mkswap /swapfile$  swapon /swapfile$ free             total       used       free     shared    buffers     cachedMem:        608476     601432       7044          0        824      88752-/+ buffers/cache:     511856      96620Swap:      1048572          0    1048572

此處不建議將swapon 寫到/etc/fstab這裡,直接寫到/etc.rc.local中更為穩妥

啟動解決...
