Strange Problem with AAF DRB connection

Hi all!

We use the DRB-Server Backend and are getting strange DRb::DRbConnErrors
lately. It started with:

too large packet 687865856
(druby:/10.0.0.10:9010) /usr/lib/ruby/1.8/drb/drb.rb:573:in `load’

and later only this one:

premature marshal format(can’t read)
(druby:/10.0.0.10:9010) /usr/lib/ruby/1.8/drb/drb.rb:580:in `load’

Do you have any ideas what that could be? We didn’t change so much
regarding aaf. Maybe we put some more fields in the index, that should
be it.

We’re using the following versions of ferret, aaf, and rails:
ferret - 0.11.3 (0.11.4 resulted in other, strange problems)
aaf - 0.4
Rails - 1.2.3

Cheers,
Hendrik

strange - the first one seems to be a request way to large, and in the
second case the request payload has been shorter than expected - are you
sure you don’t have any network issues?

Any hints on when this happens (i.e. high load, special actions) ?

Nothing like that. The strange thing is: It’s working again. We didn’t
really changed much regarding ferret…

I’ll keep an eye on this behavoir.
