[Sebastian Albert]

Hi, everyone who can help me, this log is presented to us and the router restarted. Does anyone know what it can be?

Thanks!

 - Start checking current software release on the router (installed). If it's old consider upgrading to a gold-starred release. Check wether the problems persist afterwards.

Hi Marce thanks for your respond the current version is c1900-universalk9-mz.SPA.151-4.M4.bin

Thanks

 - As stated, compare this to current available-recent  releases ; consider upgrading.

Good day,

The issue seems to be a router crash due to a memory allocation failure. 

This could be related to a software bug, so one of the things I would suggest is upgrade the router to the latest IOS available.

Did the router generate a crash file? Can you share the output of "dir all", please?

Hope this helps,

Eduardo.

Hello Edu! the router did not generate any crash info, attached the show flash all

Traceback always means it's a software bug.  

Judging from the error message, it's a memory leak.  Will get worst in the long run and if this is not corrected, the router just might crash because it ran out of available memory.
