Problems with multiple reads in rinda

I had some problems doing a number of multiple accesses to the rinda
tuplespace.

First I have filled the space with about 8000 records (5 field strings, ints
and symbols), the I run a client performing read operations on the
tuplespace.

If I run the client a few times it works fine, but after I run the client
process a few times (about 7-8 times) I lose the ring server and I have to
restart it if I want to be able to access it again.

I get the following error:

D:/apps/InstantRails/ruby/lib/ruby/1.8/rinda/ring.rb:212:in
`lookup_ring_any': RingNotFound (RuntimeError)
    from D:/apps/InstantRails/ruby/lib/ruby/1.8/rinda/ring.rb:109:in
`finger'
    from D:/apps/InstantRails/ruby/lib/ruby/1.8/rinda/ring.rb:118:in
`primary'

anybody has any idea?

I am using ruby 1.8.6 on windows.

cheers,
