How many processes are running? Just the other night sendmail "fork bombed" my server by forking into thousands of processes and slowed interactive use to a crawl. It could also be a network issue. Do a
to check the connection rate and duplex of the NIC you are connecting through. It could also be under a heavy load. Try probing around with netstat to look at your connection statistics.
I am fairly new to Unix (Sun OS) scripting with Ksh, and I could use a little help troubleshooting my script. When I run it, I get the error "if unexpected" on the function setYear. If I comment out the setYear function, I get the error "for unexpected" on the function sendEmails. This leads me... (8 Replies)

mailstats
mailstats(1) User Commands mailstats(1)NAME
mailstats - print statistics collected by sendmail
SYNOPSIS
mailstats [-o] [-c ] [-C configfile] [-f statisticsfile] [-p] [-P]
DESCRIPTION
The mailstats utility prints out the statistics collected by the sendmail(1M) program on mailer usage. These statistics are collected if
the file indicated by the StatusFile configuration option of sendmail (defined in /etc/mail/sendmail.cf) exists. The default statistics
file is /etc/mail/statistics.
To enable mailstats, you must, as root, touch /etc/mail/statistics. See the StatusFile processing option in sendmail(1M).
mailstats first prints the time that the statistics file was created and the last time it was modified. Then, the statistics for each
mailer are displayed on a single line, each with the following whitespace-separated fields:
M The mailer number.
msgsfr Number of messages from the mailer.
bytes_from Kbytes from the mailer.
msgsto Number of messages to the mailer.
bytes_to Kbytes to the mailer.
msgsrej Number of messages rejected by the mailer.
msgsdis Number of messages discarded by the mailer.
msgsqur Number of messages quarantined by the mailer.
Mailer The name of the mailer.
The display of statistics described above is followed by a separation line containing only equal sign (=) characters. After the separation
line, a line preceded with a "T" and totaling the values for all of the mailers is displayed. This is followed by another line preceded
with a "C" that lists the number of TCP connections.
To reinitialize the statistics file once a night, add an entry to root's crontab(1):
mailstats -p > /dev/null
OPTIONS
The following options are supported:
-c Try to use submit.cf instead of the default sendmail configuration file.
-C configfile Specify a sendmail configuration file.
-f statisticsfile Specify a sendmail statistics file.
-o Do not display the name of the mailer in the output.
-p Output information in program-readable mode and clear statistics.
-P Output information in program-readable mode without clearing statistics.
USAGE
See largefile(5) for the description of the behavior of mailstats when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

/dev/null Zero-lined file
