Sendmail high cpu time

[CHRIS ANORUO]

Hello everyone,


Sendmail on my K580 running 10:20 takes a high %cpu for a long period. I have sendmail 8.9.3 (PHNE_18979) installed on the server.
Can you pls explain this situation, for other servers don't have this problem.

Regards!

Hi,

What did you set as the interval (via the -q option of sendmail) to process saved messages in the queue? If this interval is set too little, there will be heavy resource utilisation.

Regards.

Steven Sim.

Steven thanks for you response.
The interval is 30minutes and is okay.

I have solved the problem, a check in the /etc/rc.log file should the following error message:

WARNING: Group writable directory /etc
WARNING: Group writable directory /etc/mail
hash map "Alias0": unsafe map file /etc/mail/aliases.db: Group writable directory
dbm map "Alias0": unsafe map file /etc/mail/aliases
Cannot create database for alias file /etc/mail/aliases
sendmail

I stopped sendmail daemon, changed the permissions on /etc to 555 and started send. Every thing is working fine, my back log of mails are coming now.
