460 days is kinda a lot -- how much free RAM do you have?
How much do I really have? I don't know. The show memory command showed only about 20M of 128M used. However, after rebooting one and comparing it's behaviour to the other cards, I found the following: -"save all" took about 5 seconds on the newly rebooted card, vs. 4-5 minutes on the cards with high uptimes. -After working on the console a few minutes, the high uptime cards became sluggish in responding, and eventually just stopped making sense. Pressing "enter" five or six times would not do anything, the seventh push would. By the time I issued a reboot, nothing was echoing back to the screen. -One arc could not even muster a login prompt; it had to be rebooted via TCM. -My DUN 718 and 720 errors went away after rebooting.
Might be a memory leak somewhere, and 460 days would be long enough to run it out. Very strange things happen when an ARC runs outta memory
It certainly seems so. I guess I'll have to start putting these things on a schedule. Kind of sucks to have to do that. I've got a 2501 here going on 3 years, and it's pretty happy. And our colo contract at the telco only allows after-hours access at about $500/hr. so I have to boot the arcs during the day, as I don't trust them that much to always come back.
It'd be interesting to see what your Radius server is logging other than accounting records (if it logs anything other than accounting records -- i.e. Cistron writes some useful stuff to a "radius.log" file.)... and also if the ARC is sending anything interesting via syslog when things fail. Without those two logs and a look at free memory I'd be completely in the dark as to what's going on...
I didn't see anything odd in radiator's logs, other than the multiple starts and stops. Syslog had (and still has) this quite often, but nothing more of note: Apr 26 22:00:56 TC-2-HARC.oldslip.inch.com At 02:00:56, Facility "GWC Modem Driver", Level "UNUSUAL":: GWCMDM_AL, slot:14/mod:24 TAPI OPEN failed Apr 26 22:00:56 TC-2-HARC.oldslip.inch.com At 02:00:56, Facility "GWC Modem Driver", Level "UNUSUAL":: GWCMDM_AL, slot:14/mod:24 TAPI_OPEN failed, retrying and Apr 26 22:14:18 TC-4-HARC.oldslip.inch.com At 02:12:14, Facility "IP Routing Process", Level "UNUSUAL":: ip_rter_del_ifb: IFB 0.0.0.0 does not exist Apr 26 22:14:30 TC-4-HARC.oldslip.inch.com At 02:12:14, Facility "IP", Level "UNUSUAL":: ip_fwd_del_ifb_rsp(): received message saying failed to delete or disable IFB of network ID 10 Apr 26 22:14:30 TC-4-HARC.oldslip.inch.com At 02:12:14, Facility "Configurator", Level "UNUSUAL":: REMOVE DYNAMIC NETWORK Failed - Protocol = 1 NetAddr = 7facfb 8, NetId = 16 Apr 26 22:14:30 TC-4-HARC.oldslip.inch.com At 02:12:14, Facility "IP", Level "UNUSUAL":: ip_fwd_remove_dynamic_net: FWD_REMOVE_DYNAMIC_NET_REQ failed : ((bad status) Interesting, but likely unrelated.

Hi,
Running ARC version 4.2.32. Uptime on all racks is 460 days, mix of DSP and quads...
In the past two weeks, we've started getting tons of "718" and "720" DUN errors on windows users ("cannot establish a dial-up networking connection" and "unable to negotiate a compatible set of network protocols" respectively). Some mac users are getting similar results but rather than an error, authentication just times out.
I see this on all chassis, and even on spans from different telcos.
Additionally, when they get in, I'm seeing multiple start records, eg:
| channel_connected_to | slot_connected_to | username | nasidentifier | framedipaddress | actual_time | acctstatustype | acctsessionid | +----------------------+-------------------+----------+---------------+ | 19 | 14 | xxxxx | x.x.x.5 | 216.223.197.116 | 2001-04-24 12:07:42 | Start | 219286853 | | 19 | 14 | mapple | x.x.x.5 | 216.223.197.116 | 2001-04-24 12:06:31 | Start | 219286853 |
Same session ID, same IP address....
Any ideas?
Is there any other more active forum for this equipment?
Thanks,
Charles
