Could you try adding the following option in Config:

#       -DCONGESTED     - turns on packet retransmission.  Use it on a
#                         congested network, where the normal operation

Sometimes you can do:  

   /usr/sbin/tcpdump -n | grep 192.168.2.100

(or whatever your IP address is) to see a particular conversation.

Sounds like it might be a network-related issue.  It's hard to tell.  Are 
these cards at 100mb or 10mb?  Does this happen even if the network is 
quiet?

Interesting. So sometimes they boot and sometimes they don't. tcpdump 
should help us determine where the difficulty is.

Happy to help.  World domination sometimes requires careful debugging! :-)
