[c-nsp] ASSERTION FAILED in file ../les/if_ng_dslsar_tx.c, line 385

[Pierre Emeriaud]

Hello list,


Since yesterday, one of my 2611XM is popping out a strange message in
the log buffer, which look like a dsl code/wic firmware debug string :

Dec  7 17:43:32.991 GMT+1: ASSERTION FAILED: file
"../les/if_ng_dslsar_tx.c", line 385


- there were a few line flaps (on WIC-1SHDSL-V3) the day before
yesterday, but it stabilized then
- I modified the NTP configuration on the router to display the logs correctly
- One hour and a half later, the router started to spit the annoying
log messge.
- Wic dsl chipset is DSLSAR.


Output interpretor doesn't show anything useful, IOS is
C2600-SPSERVICESK9-M, Version 12.4(6)T, RELEASE SOFTWARE (fc1), uptime
is 11 weeks, 5 days, 4 hours, 53 minutes.

There is also a WIC-1B-S/T for isdn backup.


Does anyone has an idea about what is this issue and what to do about it?
