Hi all,
This one has me kind of confused, as I can't find anything common to cause a slowness in the system. The slowness I'm seeing is that processes running on the system become really slow and take a long time to do what the should do. It's not a system load issue, as I see: # uptime 15:15:51 up 7:46, 8 users, load average: 0.05, 0.05, 0.00
Things like snmpd queries timing out, when restarting dhcpd the syslog output to /var/log/messages takes around 2 seconds per line.
I've looked around and can't see anything out of place, or anything obviously broken. Anyone have any ideas on this?
As a followup to this, I've noticed that the syslog is around 3-4 minutes behind the events that happen. say I login to an IMAP server, the maillog shows the login at 16:57:48 - if I breat out of that and show the date, the clock will show 3-4 minutes later (ie 17:01) - even though the line has only appeared seconds ago.
Even things such as spamassassin is taking 217 seconds to scan a 2Kb email. snmpd results to localhost are timing out - even though the process is listening.
It takes 45-50 seconds to log out of a su shell back to the logged in user, the same for becoming root via 'su -'.
I have never seen this kind of behaviour on a system before - especially when the CPU is 99% idle. Has anyone come across this type of behaviour before?
the system is: model name : AMD Sempron(tm) Processor 2800+ stepping : 0 cpu MHz : 1602.495
It has 1 Gb of RAM, and seemed to work perfectly until last nights updates.
