Hello, This mail goes to you directly because I am not subrscribed to the mailing lists. The last good build which behaves correctly is build 525 (released as Freenet 0.5) and I think early 526. Since then all the releases including build 527 (released as Freenet 0.5.0.3) does the following: It works for some time, filling up the line, then it goes into 100 % CPU usage mode, and slows down, barely using the line. After some time (10 minutes-2 hours) the 100 % CPU usage goes away, and the node again fills up the line. I think this behaviour is caused by the load balancing code, or anything which came into build 526. I backed out to use build 525, which stabilizing itself around 800 requests/hour (reported by network load window) and works continuously, as opposed to the newer builds, which sometimes work and sometimes not. I use linux 2.4.18, debian, with sun java version 1.4.0 something. Also, another issue is high thread usage. It doesn't matter if I set 120 or -120 as max. threads in freenet.conf, freenet easily goes up using 50+ connections and 200+ threads. By default bash has a 256 thread limit. The kernel has a 4095 thread limit. I set bash limit up to 2047 using ulimit, but still somehow the 256 thread limit is there, gdm starts up X window, and sometimes when I have freenet and frost running, and I want to start something from the Gnome menu, it doesn't start because of the 256 thread limit. I can start anything from bash, but sometimes even the X Window System crashes because it can't allocate threads. I will try every new builds which comes out, but back out to 525 till the 100 % cpu issue is there. If you have any solutions to these, please tell. If you need more info, and tell me what to send and how to set-up, I will do that. Please keep my e-mail address confidential, don't send it to any mailing lists.
