为啥/usr/local/bin/softlimit -m 2000000 就容易出错?

iamok

我的是rh7.3内核为
Linux localhost.localdomain 2.4.20-20.7smp #1 SMP Mon Aug 18 14:46:14 EDT 2003 i686 unknown

我用netqmail1.0.4+vpopmail+smtp-auth补丁+mysql

奇怪的是我的/service/qmail-pop3d和/service/qmail-smtp中的run脚本中如果有/usr/local/bin/softlimit -m 2000000

就会出错,pop3的症状是error while loading shared libraries: libc.so.6: failed to map segment from shared object: cannot allocate memory


而smtp的症状是不能验证...


求医..

付上脚本:

2. #!/bin/sh
   
3. 
   
4. QMAILDUID=`id -u qmaild`
   
5. NOFILESGID=`id -g qmaild`
   
6. MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
   
7. LOCAL=`head -1 /var/qmail/control/me`
   
8. 
   
9. if [ -z "$QMAILDUID" -o -z "$NOFILESGID" -o -z "$MAXSMTPD" -o -z "$LOCAL" ]; then
   
10.     echo QMAILDUID, NOFILESGID, MAXSMTPD, or LOCAL is unset in
    
11.     echo /var/qmail/supervise/qmail-smtpd/run
    
12.     exit 1
    
13. fi
    
14. 
    
15. if [ ! -f /var/qmail/control/rcpthosts ]; then
    
16.     echo "No /var/qmail/control/rcpthosts!"
    
17.     echo "Refusing to start SMTP listener because it'll create an open relay"
    
18.     exit 1
    
19. fi
    
20. 
    
21. #exec /usr/local/bin/softlimit -m 2000000
    
22. exec /usr/local/bin/tcpserver -v -R -l "$LOCAL" -x /etc/tcp.smtp.cdb -c "$MAXSMTPD" -u 89 -g 89 0 smtp /var/qmail/bin/qmail-smtpd mailsystem.xxxxx.com /mailroot/mailbox/bin/vchkpw /bin/true 2>;&1

不好意思..找到问题所在了...

qmail-smtpd的启动脚本是按 Life with qmail中讲的 写的，直接copy的，也没仔细看。  

qmail-smtpd，启动的部分设置了  

exec /usr/local/bin/softlimit -m 2000000 \  


这个默认是 2m 的内存。这个太小了，导致 vchkpw 导入 libc.so.6这个库的时候，内存不够用。  

我现在设置了20M，就什么问题都没有了！！！
