Re: [Help-gnunet] [BUG] Internal error: assertion failed

[Christian Grothoff]

I think I fixed it (SVN HEAD).  It's a bit strange that this could happen -- 
what was going on was that gnunetd was queueing more than 60 MB of content 
(in, presumably, chunks of about 32k) for some client (gnunet-download or 
gnunet-gtk) and the client just did not read the data (at least not fast 
enough).  I've now changed the code to block (wait for the client) instead of 
buffering (and then hitting the buffer-size threshold, which is where it 
died).

Naturally, this raises the question whether there was a problem with the 
client (deadlocked, unusually slow) or if this was just really a scheduling 
issue (no CPU for client, tons of results received quickly by gnunetd).  
Anyway, the specific crash should be fixed now.
