RE: [qmailtoaster] server acting strange

[António Pedro Lima]

Probably ram... Everytime I have a machine getting strange, I allways point
to RAM first. I'll sub the RAM and see if it was "only" that...

Thanks for all the hints

More like 'if' there are any processes eating the CPU. The CPU loads
averages are a peculiar metric. They reflect average wait times (in
seconds). CPU saturation will certainly cause higher load averages, but
other factors can too. I think that bad RAM is a good guess. Your load
averages are awfully high.

I would tend to agree with the possibility of bad RAM.  And if webmin
logs the CPU usage like top does, then you're CPU loads are higher than
normal.  Can you run "top" at the CLI and see what processes are eating
the CPU time?

I have just increased daemons…

Happens less but still happens.

 

System hostname mail.itfor.org 
Operating system CentOS Linux 5 
Webmin version 1.410 
Time on system Thu Jul 24 10:25:54 2008 
System uptime 1 hours, 0 minutes 
CPU load averages 32.23 (1 min) 20.95 (5 mins) 17.45 (15 mins) 
Real memory 942 MB total, 429.82 MB used 
Virtual memory 1.94 GB total, 0 bytes used 
Local disk space 106.41 GB total, 17.21 GB used 

 

This is from my webmin. I suppose it should be enough for the server. I will
put it mor RAM, but I suspect there is something wrong with it.
It happen suddently. I would understand that daemons wouldn’t be enough if I
have added more users. But it started acting like I described apparently
without reason.

I’m getting clueless…

That's a good start, but you still haven't said what your server load is
like. How many users, how using IMAP, how many using POP3, etc.
You may also try increasing the courier daemon in
/etc/courier/authlib/authdaemonrc (default is 15).  Here's the comments from
the file:
# You may need to increase daemons if as your system load increases.
Symptoms
# include sporadic authentication failures.  If you start getting
# authentication failures, increase daemons.  However, the default of 5
# SHOULD be sufficient.  Bumping up daemon count is only a short-term
# solution.  The permanent solution is to add more resources: RAM, faster
# disks, faster CPUs...

That spamdyke log message is not a problem. You can ignore it.

What is your load like? This may be caused if you are reaching your 
maximum number of connections for mysql.

Hi again.

 

My server is acting strange today.

Outlook keeps asking for login and password. Where should I look?

 

 

Thanks,

 

António Lima

Check the list archives. There was a post a while back regarding this. There
is a MS KB article which describes a registry modification which might solve
the problem.

Oh, and it's most likely that it's Outlook, not your server, which is acting
strangely. ;)
