Re: [freenet-support] freenet load always >100%
I'm not seeing this but now that the world seems to have "discovered" my node, my JVM keeps dying with out-of-memory and NULL pointer exceptions. I still have plenty of (virtual) memory left, so something else must be serving as a "cap" on the memory that java can get. This might be a java tuning parameter or a kernel setting (I'm using FreeBSD 4.9-STABLE), but if anybody has any clues I'm appreciate it. My current solution of "shutting down freenet every time it happens and restarting it" is getting old fast especially since that's getting to be about every hour now.

I run FreeBSD, with JDK 1.4 (jdk-1.4.1p4_1) and 4.9-STABLE kernel.
Free *is* very slow for me but I don't see loads > 100%; in fact, the load
numbers always seem fairly plausible. Just a data point to tell you it's not
universal.
