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 +
