不好意思,在bsd没有人理,在这里再发一次。
我使用qmail+qmail-scanner+clamscan 在freebsd5.0上。384M物理内存,512M交换分区。clamscan 为0.7版本
以下用top得到结果:

其中Swap不断的减少。最后在/var/log/message里面有以下记录:
May 11 16:11:11 mail ntpd[396]: kernel time discipline status change 2041
May 11 16:13:52 mail kernel: swap_pager: out of swap space
May 11 16:13:52 mail kernel: swap_pager_getswapspace: failed
May 11 16:13:52 mail kernel: pid 1976 (clamscan), uid 0, was killed: out of swap

May 11 16:14:07 mail kernel: swap_pager_getswapspace: failed
May 11 16:14:08 mail last message repeated 118 times
May 11 16:14:08 mail kernel: pid 1988 (clamscan), uid 0, was killed: out of swap

space
May 11 16:14:21 mail kernel: swap_pager_getswapspace: failed
May 11 16:14:29 mail last message repeated 462 times
May 11 16:14:29 mail kernel: pid 2032 (clamscan), uid 0, was killed: out of swap
最后系统无法响应任何操作从而系统崩溃。
感谢每一位朋友的回复,谢谢 |
