Re: [xmlblaster-devel] Socket test, was LOCAL not working?

[Michele Laghi <laghi at swissinfo.org>]

Hi,
are'nt these two distinct problems ? I tested a little with corba and it 
appears that the deadlock happens always after having cleaned up some 
threads (lastDiff is often negative just before). I laid in a list of 
the threads before and after and the ones having been cleaned up are the 
corba RequestProcessor-xxx threads.

See the attachments (threads1.dat is before cleaning up and threads2.dat 
is after).
