Red Hat stalling

[sheds]

Hi. I got a red hat installation running named. The problem started about 3 and a half months ago. It was working fine since forever. Now, it's all working slow and that causes, i think, named to stop resolving. I have cleared logs in /var/log to see if it's a disk full problem, so far, i don't think thats the MAIN problem. I also ran top, and to my surprise, there's a process called 'sendmail' that appears like 20 times in the same window when running top. I researched about sendmail, but the info is just not near enough for me to troubleshoot.

Another interesting thing is that maillog is still getting filled by messages regarding sendmail. I stopped the service using this steps:
# service sendmail stop
# chkconfig --level 12345 sendmail off
I would think that the second step there would stop the service from running, but somehow it is still being invoked by another. At least that's what it seems. So, what i would like to do next is to figure out why is it still running as some kind of background job. I guess it's running as a bg job, taking into account that sendmail does not appear in the list when typing the 'top' command.

Probably another service is configured to send an email on certain situations...
...sendmail was doing its job, so you must find the program sending all that emails.

You can start stoping some service, for exluding some...

Now I ask you: why you run named and sendmail?

I didn't put sendmail to work. Um, only named is supposed to be working on that server. I don't see the reason why sendmail should be sending all that junk. Let me put the maillog lines there so you can have a look at what it's doing.

That's a small sample of what i see in /var/log/maillog. Hope it helps you out.

Probably sendmail is not configured, so it logs all that stuffs...

Deferred: Connection refused by [127.0.0.1]

Apart that, named try to notify abnormal situation sending email to the root@localhost, and this cause the logs...

I'm not helping you much. But you have 2 possibilities:
- setup sendmail (difficoult task, but it can be easy for local mail) for reading what named wants say... and correct situation
- understand directly named problem...

Now... why don't uninstall sendmail?

[sheds]

Because i don't know what repercusions it may have on the system. I really don't want to mess it up, not now because i just fixed, if i can say that. I would be easier and i already know the command line instructions to do so, but i think it's better to know exactly how to configure and find out why is it logging like crazy.

Perhaps something wrong with Sendmail setting or Firewall setting.
