[GNUnet-developers] RE: testing gnunet-0.5.0

[Jan Marco Alkema]

Hello Niklas,

Thanks for your feedback ---)

I believe in the concepts of gnunet. We should do a lot of testing, scale it
up to more realistic user numbers, suggest better things in gnunet. All
together we can make a very superiors "file sharing system"...,

Greeting Jan Marco

N.B. I see on both Linux server zombie processes, 39 on mine ADSL Linux
server and 8 on mine cable Linux server... See Appendix B.

The same thing happened to me.  I didn't notice it had segfaulted
yesterday, but when I tried to start it today it just segfaulted right
away.  When run with -d it gave me a fatal error that pthread_mutex_lock
(or something like that; I didn't save the error message unfortunately)
failed and it was avoiding deadlock.

Removing the hosts directory was enough to enable it to start again, so
my guess is the lock that was not released properly was in one of those
files.
