Solaris

Hello,

I am using Solaris 10 and I'm geting the folowing error in /var/adm/messages.

Code:

Feb 12 09:01:18 srp21ce1 uamod: [ID 518202 kern.notice] NOTICE: (uamod480 @ Q 0x600159db710) set threshold to default values

Can you help me understand from where it can come?

Thank you.

what hardware model is this? Since when are you getting this messages? What recent changes done to the existing system?

It is a Netra T2000 Sun server. I noticed the messages only today and from my knowledges no modification was perform on the server.

I have some other servers in similar configuration, but the uamod messages are not present on /var/adm/messages.

Thank you.

switch to ALOM, check the firmware version please and post it here.
It should be >6.5 ot >=6.7
sc>showhost

I found the answer:

The above events are output by UAMOD to indicate that a local SCTP association was deleted and recreated. They usually come along with deactivation and deletion events of SCTP associations and IP links, for example:



19-Feb-2010 10:56:14 srp21ce1.ss7_L3MTP Error 00069 00063 IP signaling link LINKTB has been deactivated

19-Feb-2010 10:56:14 srp21ce1.ss7_L3MTP Info 00069 00320 The M3UA lset LKICTB11 is down (All m3ua links in the linkset are down.)

19-Feb-2010 10:56:14 srp21ce1.ss7_L3MTP Error 00069 00061 SCTP association LINKTB has been deleted



19-Feb-2010 10:56:30 srp21ce1.ss7_L3MTP Info 00069 00060 SCTP association LINKTB has been created

19-Feb-2010 10:56:31 srp21ce1.ss7_L3MTP Error 00069 00061 SCTP association LINKTB has been deleted



19-Feb-2010 10:58:25 srp21ce1.ss7_L3MTP Info 00069 00060 SCTP association LINKTB has been created

19-Feb-2010 10:58:27 srp21ce1.ss7_L3MTP Info 00069 00062 IP signaling link LINKTB has been activated



The UAMOD events are output either from manual deactivation/deletion/creation of IP links or as a result of the remote side aborting the SCTP association. Either a wireshark or tcpdump trace can verify whether the SCTP association is being aborted as a result of the remote side. If in fact the SCTP associations are being aborted from the remote side, further investigation on the remote side would be needed in order to determine the root cause.
