It looks like if they don't, it may take some time to figure this one out or start reducing the multiloading of the SCM... assuming a primary is managing 2 other TNT's. I suggest the 9.0.6 since you said that 9.0.9 was what you're using and 9.0.4 didn't do it for you either. Sometimes, a bug fix addressing some issues can cause a cascade of other issues to either resolve or appear. 9.0.6 , IMHO, is a stable code and is patched for the SNMP vulnerability. So, that is the one that made sense to me. If that doesn't work and you still want to approach the TAOS issue, you can always try 9.1.5. I believe Lucent will give that to you free if you can prove you need it for a possible bug fix. It might give you some in-roads to them helping you figure out the problem if they have to give you something free if they don't help you. ;-) Just out of curiosity, do you have more than 1 multishelf setup? Also, Lucent will likely tell you that they do not support multishelf anymore (in fact, 9.1.x might not even support it! - better double check on that). They may even tell you that your issues are the reason, in part, that multishelf is "no longer supported". Who knows? It's worth a try. - David -----Original Message----- From: Øystein Homelien [mailto:oystein at homelien.no] Sent: Monday, November 18, 2002 4:05 PM To: DPascarella at solunet.com Cc: ascend-users at bungi.com Subject: RE: [Ascend] (ASCEND) ascend tnt hdlc2ec cards _hanging_ temporar ily On Mon, 18 Nov 2002 DPascarella at solunet.com wrote: > Have you done the old swap slot/card/chassis thing?

Are you running 9.0.9 for a > specific reason or can you downgrade to 9.0.6? We are running 9.0.9 because we always have various small issues that we would like to fix (bad connects, tnts need to be rebooted every week or they start refusing more and more isdn calls per hour, etc.). So we try to keep running the newest bugfixes if there is an indication that something we need to fix has been fixed in the release notes. Is there anything specific about 9.0.6 that would make it a good release to test? As I said, we have also tested with 9.0.4 (that we ran previously, without having this problem) but the problem still persists. I am not sure when the problem started appearing, since as you see uptime and logs show nothing about the problem. We just discovered it because customers complained about packet loss, and then we started debugging more closely. Thanks for your reply though :-) I had hoped that a Lucent employee would spot us and start taking care of this, though... > > It's nice when you ask a bunch of questions and get even more back, eh? > > Just probin'. > > - David > > > -----Original Message----- > From: Øystein Homelien [mailto:oystein at homelien.no] > Sent: Sunday, November 17, 2002 1:42 PM > To: ascend-users at bungi.com > Subject: [Ascend] (ASCEND) ascend tnt hdlc2ec cards _hanging_ > temporarily > > > Anyone had problems with something like that?
