NOQUEUE: low on space ( have 0, SMTP-DAEMON needs 101 in /var/spool/mqueue)

hi,

I'm in Solaris 2.8 env. When i'm trying to add a ftp user account ,
encountered "no space in disk" .. couldn't create any user. Then check the fs disk space with "df - k " and /var/adm/syslog .. got the below message.


Jun 9 03:10:53 mail sendmail[238]: [ID 801593 mail.alert] NOQUEUE: low on space
(have 0, SMTP-DAEMON needs 101 in /var/spool/mqueue)


Cudn't find any files in /var/spool/mqueue. What is core files , where we can find that ?

FS statistics :

# df


/ (/dev/dsk/c0t0d0s7 ): 82486 blocks 380813 files
/proc 0 blocks 3843 files
/dev/fd 0 blocks 0 files
/etc/mnttab 0 blocks 0 files
/var/run 1342224 blocks 26540 files
/tmp 1342224 blocks 26540 files
/export/home 8822732 blocks 646047 files

# df -k

/dev/dsk/c0t0d0s7 2645310 2604083 0 100% /

/proc 0 0 0 0% /proc
fd 0 0 0 0% /dev/fd
mnttab 0 0 0 0%
/etc/mnttab
swap 671064 0 671064 0%
/var/run

/dev/dsk/c0t0d0s0 5109622 698256 4360270 14%
/export/home



How & what to delete to get more space .. ? Jus known that,a copy of all mails sent will be in send-mail folder, What z the location for send-mail directory?

Thanks in advance

Core files are files created when an error occurs - someone running an application closes it incorrectly and the system can't send anymore output back to the user - creates a core file (usually in their home directory) - Applications or services can also create core files - I was running console command for a server and created a core file
medusa% file core
core: ELF 32-bit MSB core file SPARC Version 1, from 'cconsole'
medusa% ls -l core
-rw------- 1 tghunter sysadmin 1941504 Jun 7 11:32 core

Another user created one using HP OpenView -
# ls -l core
-rw-r--r-- 1 gmlaroe ncc 1596208 Jun 10 07:02 core
[root@somewhere]:/home/gmlaroe
# file core
core: ELF 32-bit MSB core file SPARC Version 1, from 'ovw'

Note that each of these uses up quite a bit of disk space.

Another area you can look at (because you are running Solaris 8) is all the extra packages that come with Solaris 8.
/usr/apache
/usr/perl5
/var/apache

If you don't need them, they could be removed

If you don't need man pages, remove them by searching for them first (insure you don't care about them) and then remove them.

It is up to you to figure out if you need these files - it's your system and you should know what you do or do not need.

You can do a man on core -

NAME
core - core image file

DESCRIPTION
The operating system writes out a core image of a process
when it is terminated due to the receipt of some signals.
The core image is called core and is written in the
process's working directory (provided it can be; normal
access controls apply). A process with an effective user ID
different from the real user ID will not produce a core
image. This is also true for a process with an effective
group ID different from the real group ID. Set-user-ID and
set-group-ID programs do not produce core images either when they terminate, since this would cause a security loophole.

Also go to www.sendmail.org and read the FAQs. If this server is for mail only, you would want to insure you turn off anything else (telnet, ftp, remote services...). Check the web for security issues.

Another thing - check the size of your /var/adm/messages* file(s).
It may be they are filling up your / file system. You wrote that /var/spool/mqueue was empty so it isn't email doing it.

Which email are you using - Sendmail or something else?
