system limits

hi Vlad,

twice on a live network we have seen the error message about the system limit
being reached, i.e:

=ERROR REPORT==== 1-Apr-2002::11:01:36 ===
Too many processes

In both cases it was public holiday and noone was able to check the status of
the node to see how many processes there are & who eats them up.  After that
there was a complete reload & all info lost.  We have been investigating this
for a while, but the progress is very slow.

So, I would be very curious to hear more on this subject also.

Regards,

    Helen
