DH parameter generation hanging

[Riccardo Veraldi]

Hello,

freeradius 2.1.10 here on soekris net5501

radiusd: FreeRADIUS Version 2.1.10, for host i386-unknown-openbsd4.9, 
built on Mar 11 2011 at 11:20:43


the problem is when starting freeradius, it hangs forever when 
generating DH parameters.
Any clue on this problem ?

thank you

Rick
