Slackware 13.1 hangs on every 15 minutes
Sorry if there is a such topic, but I'm in a bit of a hurry.

So the situation:

I have a small Slackware gatway/web server/mail server. Few days ago I upgraded it to 13.1 and from this morning I have the following problem:

After restart the server works for 15 minutes (htop showed max uptime of 15 minutes 15seconds) and than it hangs (or at least the ssh/web/imap connections are lost)

I have checked all logs but there is no problem!

Neither in syslog, nor in messages. The inittab is set to runstate 3 ...

I have stoped all services I don't nead ...

Have a look in the /etc directory at any /cron.*/files and see if anything there runs at about the 15 minute mark.

Nothing there ... the only crontab is root's.

Processor sleep states?

Trying to recompile kernel ...

I hope it wont hang ...

CPU is Pentium 4

It works exactly 15 minutes and 15 seconds ... no metter what!

You stated or at least the ssh/web/imap connections are lost. Does the machine actually hang, or does the network drop connection, then reconnect? If it's the network which nic? One of those buggy intel e1000's with a bad eprom?

Lucifer4o 06-02-2010 04:07 PM

It is the whole system!

The problem is I don't have fisical access to the machine (it is 500 km away). I only have hands and eyes there ...

A wild stab in the dark, but it may have something to do with this entry in /etc/rc.d/rc.M

# Screen blanks after 15 minutes idle time, and powers down in one hour
# if the kernel supports APM or ACPI power management:
/bin/setterm -blank 15 -powersave powerdown -powerdown 60

Tommorow (that is later today) I'll test it ... you are probably right, dough ...

Lucifer4o 06-03-2010 01:43 PM

It's not that ... deamn! I'm going out of options ...

If you lose the connection how can you be sure that it is a system freeze? Couldn't it be just losing the connection? Maybe you should take a second look at the network settings.

Lucifer4o 06-03-2010 03:15 PM

Easy - seted up a cron job to reboot the mashine ... it didn't. So the system is not operational ...

Ilgar 06-03-2010 03:26 PM

How about trying the boot options acpi=off and/or noapic? It would have to be a weird hardware problem to occur exactly after 15 mins 15 secs but who knows...

Just to be sure. Did you upgrade from Slackware 13.0? If so, did you follow the steps in UPGRADE.TXT?

Finally, as you are running a server, did you make a full installation and if not what you didn't install? I'm asking because it could be that you didn't install a new library.
