Well, I updated the node, added the LD_ASSUME_KERNEL environmental variable, restarted the node, and then went to doing other things. Heavy CPU usage things. No problem, since I've niced Freenet to 19. Well, guess what ? When I came back, Freenet had restarted itself.
I guess that the deadlock protection had detected that whatever it was watching wasn't responding in time, and rebooted the node, which - since the CPU was loaded - took a loooong time to come back online, and even once it had, would simply restart again. So: would you please turn off deadlock detection if LD_ASSUME_KERNEL is set ? You can detect it, I know, since the warning on the proxy homepage is not displayed if you do. Oh, and I have 10 nodes that have updated to 758. They are all backed up. ot good, not good at all :(.
