Matthew,I don't monitor the node that closely. The reason for the crashes varies. It seems to usually be a "null pointer exception". Other times it just crashes out with no warning. Other times it runs out of disk space. When that happens the entire Freenet installation virtually self destructs, corrupting key files, mostly the persistent temp files and the .db4o database. I have to totally wipe those to recover the node. The datastore seems to survive all crashes ok. Freenet really should handle running out of disk space better than this.
So I've turned the log level down to minimum to help prevent runaway disk usage. Hence I no longer see much info on what might have made the node crash. I did manage to increase the size of the partition that Freenet runs from by about 2GBytes and decrease the size of the datastore by 1GByte. So far no more running out of disk space.

Usually I have toshut the node down completely for about two days. When I restart it, after about 10 minutes it starts getting connections. One time I downloaded a new seednodes.fref file and that seemed to get the connections started again. I think there is a bug where the node keeps trying to contact one or two nodes on IP addresses that are no longer valid.

Those two IP addresses arenot reachable and the node is stuck in a loop trying to get to them. Oneother temporary fix was to edit the seednodes.fref file and removethe nodes with the unreachable IP addresses. Freenet 0.7.5 Build #1233 build01233 Freenet-ext Build #26 r23771 # Java Version: 1.6.0_15 # JVM Vendor: Apple Inc. # JVM Version: 14.1-b02-92 # OS Name: Mac OS X # OS Version: 10.5.8 # OS Architecture: x86_64 Sure seems like a serious bug to me.Sounds like a serious bug in your internet connection. We do indeed repeatedly send handshaking packets to all our peers' IP addressesand this is normal and expected behaviour if two of them have invalid addresses.The first of those IP addresses listed looks like my node. I'm notsure why it made that one public; it should be using evanbd.dyndns.org. That IP is indeed not routable to the outside world; apparently my noderef is from when I was running on my father'sstrangely configured network (something about needing to be able toVPN into networks that collectively used all the various reserved-for-private nets address spaces, so he chose something unreserved that he knew to be unroutable).My updated noderef is below. I've manually examined it for obviouserrors. I've left the ip address in it; that is the correct external ip for my node. However, it's a dhcp address (though an infrequently changing one), so it should probably removed to leave only the dyndns name if that won't cause any problems.

Still seems like a bug. A guess: Both those noderefs seem to be dynamic DNS type domain names. If the node's IP address changes and the dynamic DNS entry is notcorrectly updated, it triggers some bug where another node only triesto contact those two seednodes.I entered Evan's new node ref into my seednodes.fref file. The otherunreachable node ref has been deleted from the seednodes.fref file. We'll see what happens. PaulDo you still have connectivity problems with Freenet?
