Hello,

I have installed tahoe on +10 servers. I run into this situation, on  
two of the servers I cannot start the peer software, the errors are  
similar:

	]

The tahoe.cfg file is standard, I have not set anything special on  
these two nodes compared with the others.

Can somebody provide a clue how to solve this?

Regards,
Adrian
