RE: Mbufs leak- inputs


Hi,

Thanks to all them , who have responded.

The issue is resolved. The bsd tcp/ip timers were not working on our code base ( hence the ip-reassembly freeing  timer was not kicking in ).

We have updated our file from ecos cvs , hence  with the patch  in  ( ecos-2.0--src\packages\net\bsd_tcpip\v2_0\src\ecos\timeout.c ) file our problem is resolved.

Thanks
Saritha.

Hi Saritha,
I've been having the 'out of MBUFs' problem as well.
I had not been able to determine why. When my system reports it though 
it does not recover. I can reproduce your problem as you describe.
It only takes about 10 pings for me to see it appear but at least
the system does not lock up in this case.
