tcp_timer: strange state messages occuring reason unknown

[Jaris Detroye]

I am finding the following messages in my network logs:

Does any of this ring a bell with anyone?

Hi


You should get the latest ARPA Transport and Streams Patches

'Location : 00123'

I believe refers to TCP port 123 which is used by NTP.

Check 123 in /etc/services on client and server.

Know your ntp server?

ntpq -p (* list out *)

/sbin/init.d/xntpd start/stop

Steve is right, for 11i, this was corrected in the ARPA patch, of which the latest is PHNE_28089. It contains the fix to eliminate the bogus timer state message.

Steve is correct. It's apatch issue. I found this at http://archives.neohapsis.com/archives/hp/2002-q2/0027.html

Symptom:
Message getting displayed on console:
tcp_timer: strange state (-6) [5767,d425] TCP_CLOSED
Defect Description:
The tcp connection was set to TCP_CLOSED without stopping
the timer.


Resolution:
When changing the tcp state to TCP_CLOSED in
the case of a connection waiting to be accepted
the timers on the connection are cleaned up.

I think they are talking about PHNE_24506.

Sorry guys, I have PHNE_26771 which is the latest ARAP patch for 11.0.
Any other ideas?

[Michael Steele_2]

Sounds like you've got some latency / delay in your network and its time to start evaluating. This would inlcude dropped packets, collisions, and time outs, socket overflows and retransmissions.

Making sure the same speed and duplex is being used through out the network beginning with your NIC to switch connection is important.

lanadmin -x PPA

netstat -m

netstat -s -p tcp

sar -u 5 5 (* %idle = 0 *)

[Ron Kinner]

Both 24506 and 28089 are for 11.11. Doesn't appear that there is a fix for 11.0. Perhaps it's time to talk directly to HP about it. Refer them to JAGad93560.
