I hate it when I crash my email server. Here's what tailing /var/log/qmail/qmail-smtp/current gives me: [root at toast jack]# tail /var/log/qmail/qmail-smtpd/current @400000004e9ddbd031610f54 tcpserver: status: 0/20 @400000004e9ddbd72c767c04 tcpserver: status: 1/20 @400000004e9ddbd72c7ab60c tcpserver: pid 12039 from 210.76.164.235 @400000004e9ddbd739a20d1c tcpserver: ok 12039 mail.toast.com:209.216.9.56:25 mail.cdfy-china.com:210.76.164.235::2804 @400000004e9ddbd81c826894 Can't load '/usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/DB_File/DB_File.so' for module DB_File: libdb-4.3.so: failed to map segment from shared object: Cannot allocate memory at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/XSLoader.pm line 70. @400000004e9ddbd81c827c1c? at /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DB_File.pm line 251 @400000004e9ddbd81c828004 Compilation failed in require at /var/qmail/bin/qmail-scanner-queue.pl line 480. @400000004e9ddbd81c8287d4 BEGIN failed--compilation aborted at /var/qmail/bin/qmail-scanner-queue.pl line 480. @400000004e9ddbda0c5bb434 tcpserver: end 12039 status 0 @400000004e9ddbda0c5bbfec tcpserver: status: 0/20 So I checked the permissions: [root at toast jack]# vi /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DB_File.pm [root at toast jack]# ls -al /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DB_File.pm -rw-r--r-- 1 root root 63389 Jun 13 02:58 /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/DB_File.pm [root at toast jack]# ls -al /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/DB_File/DB_File.so -rwxr-xr-x 1 root root 54216 Jun 13 02:58 /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/auto/DB_File/DB_File.so [root at toast jack]# ls -al /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/XSLoader.pm -rw-r--r-- 1 root root 10461 Jun 13 02:58 /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/XSLoader.pm and did a netstat: netstat -na | grep :25 tcp??????? 0????? 0 0.0.0.0:25????????????????? 0.0.0.0:*??????????????????

In my case the problem was with submission service: ]# head /var/log/qmail/submission/current @400000004e8632f1279bcb1c tcpserver: status: 0/200 @400000004e8c8d660a78233c tcpserver: status: 0/200 @400000004e8cc0f40b7c931c tcpserver: status: 1/200 @400000004e8cc0f40b7fd70c tcpserver: pid 20116 from 127.0.0.1 @400000004e8cc0f40b809674 tcpserver: ok 20116 mx.webers.com.br:127.0.0.1:587 :127.0.0.1::60821 @400000004e8cc0f40b8dd514 /var/qmail/bin/qmail-smtpd: error while loading shared libraries: libselinux.so.1: failed to map segment from shared object: Cannot allocate memory In my case, the solution was to increase memory, softlimit line on /var/qmail/supervise/submission/run: exec /usr/bin/softlimit -m 64000000 \ <==== increse this value /usr/bin/tcpserver -v -R -H -l $HOSTNAME -x $TCP_CDB -c "$MAXSMTPD" \ -u "$QMAILDUID" -g "$NOFILESGID" 0 587 \ $SMTPD $VCHKPW /bin/true 2>&1 Maybe it would be useful for your case too.
