DNS server /var/spool issue
Hello all
Currently I am working in a live production environment with 100+ Solaris servers . The environment has one DNS server and one SMTP server.

The problem that I am facing since the past 2 months is that the /var/spool/mqueue on my DNS server keeps getting full i.e. mails with name starting with qfr & dfr keeping on gathering up and I have to manually go and delete these mails.
Some sample outputs of these mail files are given below:

Code:
root@opaldn0: /var/spool/mqueue $ cat dfr238L5KN024487
Your "cron" job on mercury0 couldn't be run
can't change directory to your home directory.
Your commands will not be executed.
The error was "No such file or directory"

Code:
root@opaldn0: /var/spool/mqueue $ cat dfr237i8iY018725
Your "cron" job on mercury1
/med/appl/debmed/bin/runReadgFileS1.sh

produced the following output:

create_log_dir.sh is already running.


Code:
root@opaldn0: /var/spool/mqueue $ cat qfr237oAtK019510

It seems that the issue is somewhat related to crons.

Does anyone know how I can get rid of such mails ? I have to empty the /var/spool/mqueue directory every 7-8 hours since the number of mails reaches 50,000 +

desproxy-dns

desproxy-dns(1) 						   User Commands						   desproxy-dns(1)

NAME

       desproxy-dns - DNS for dynamic connections

SYNOPSIS

	  desproxy-dns dns_server proxy_host proxy_port

OPTIONS

       None

DESCRIPTION

       If you have direct DNS access then you don't need to do anything else.  You know you have direct DNS access if you can resolve host names
       to IP addresses.

       NOTE: as desproxy-dns listens in port 53 (which is less than 1024) you may need administrator privileges to exec desproxy-dns (in fact if
       you are running UN*X, you actually have to run desproxy-dns as root).

       OK, so you have a dns server accessible now. But your computer doesn't know anything about that. You must configure your network
       accordingly (again, need to be root in UN*X).

       Edit /etc/resolv.conf and add the line "nameserver 127.0.0.1". You don't have to restart anything. Just test ping and see if it works.

ENVIRONMENT

       None.

FILES

       None.

SEE ALSO

       dnsproxy(1), ping(1)
