Re: [ECOS] Problem with IP Stack ...

Since you explicitly ask for more information :-) .....

We updated to yesterday's version of RedBoot and it made a (small) difference.
The problem of ECOS crashing still exists, but now I see several "out of
CLUSTERs" messages even without the redirection of the COMM channel in place
(the messages are going over IP).

What we found is that at the time when the clusters suddenly jump, the number of
MBUFs is also increasing. There seems to be a loss of 36 clusters. After the
first time the free clusters go to 0 they never go above 27. 36 + 27 gives 63
which is the total number of available clusters. Does that mean anything to
anybody of you?

In addition to the lost clusters we also lose 72 MBUFs (36 x 2). Could it be
that MBUFs that for some reason never get free'ed are `holding' clusters? It is
also strange that, although the (indicated) MBUFs increase from 0 to 72, the
(indicated) pool memory does not decrease ??? Accident?

Any comments/help on that topic would greatly be appreciated.


best regards,
Tom
