This time I finally got a readable backtrace and :crash location (by the way, I had to comment out the crash handler to :get sensible core dumps): : :Program terminated with signal 11, Segmentation fault. :#0 dht_find_bucket (id=0xbff39f9c) at routing.c:1206 :1206 result = (val & mask) ? kb->one : kb->zero; : :So kb seems to be NULL... That's not possible unless `root' is also NULL. But otherwise kb can never be NULL (since we escape the inner loop as soon as `result' is NULL). However, `root' is only reset back to NULL in dht_close(). So if it is becoming NULL during operations, it means there is a memory corruption. I am not experiencing any problem with the DHT code here and I have very large uptimes (> 30 days). The only time I stop gtk-gnutella is when I need to upgrade... And I naturally switched the DHT code on! The next time it crashes, can you please show me the value of `root'?

Have you considered that this code is reached even if dht_initialize() was never called? > I am not experiencing any problem with the DHT code here and I have very large > uptimes (> 30 days).

Also you can neither disable or enable it during run-time because the code is widely ignorant of the setting causing crashes when changed at run-time. -- Christian ------------------------------ Message: 4 Date: Thu, 27 Nov 2008 20:46:20 +0000 (UTC) From: Raphael_Manfredi@...

Ouch, my fault. Of course, this is the problem. It's been fixed in r15883. :Yes, but it's disabled by default for many good reasons. Also you can neither :disable or enable it during run-time because the code is widely ignorant of :the setting causing crashes when changed at run-time. Indeed, support for switching the DHT on and off at runtime is not finished.
