Hi all, I am running qmail on mail server (RH 7.2) with ldap, recently I have noticed that I am getting following error in my log file (/var/log/maillog) . The log type is splogger. Following is content of the logfile   Jul 28 23:59:47 servername qmail: 1027880987.222777 starting delivery 142997: msg 276104 to local [EMAIL PROTECTED] Jul 28 23:59:47 servername qmail: 1027880987.222801 status: local 2/500 remote 2/500 Jul 28 23:59:47 servername qmail: 1027880987.254444 delivery 142996: success: did_1+0+0/ Jul 28 23:59:47 servername qmail: 1027880987.254536 status: local 1/500 remote 2/500 Jul 28 23:59:47 servername qmail: 1027880987.258412 delivery 142997: deferral: Aack,_child_crashed._(#4.3.0)/   What I understand that, it has something to do with the qmail-local or some quota-warnning program!. I would be grateful if you can help me to understand & resolve this problem.   Thanks in advance.   Praful
