You seem to have quite a lot of memory (I asked because I supposed
something like 64MB). But as 'free' shows, you use it all either for the
applications or by the kernel buffering. Are you still using 2.2.10 ?
Maybe upgrading to something newer will solve your problem; however, I
don't have much knowledge in this area, so other oppinions are welcome!

In one of your previous messages, you said that using 3c59x-bc-1.0 you
were able to run for more than 7 hours, but with error messages. Now you
say that it halts later and give a figure of 2 hours. Are you using the
same driver ?

No, it's due to out-of-memory situation.
