added 3.5.11. sorry haven't got around to testing this yet. has it reoccured in 3.5.11? a backtrace from the running program would be useful too if it reoccurs. http://www.gentoo.org/proj/en/qa/backtraces.xml I installed 3.5.12, yes, it is still happening. lftp runs nightly to ftp a backup to another machine, and a significant fraction of the time, it is still running the next morning and using up 100% CPU. The ebuild for the versions which don't have this problem all seem to have disappeared! I don't know how I can downgrade to a non-buggy version now. hoping this was fixed in later version. I really did loose many months last year just doing other stuff so apologizes for the delay. It may be fixed - I am not sure. I ended up adding a kill script to my crontab so that if lftp runs for more than a few hours it will be killed. I could disabled that and see if it's still happening, if you want. I think it must be some particular feature I am using - or the flakiness of the FTP server I am uploading to - which is triggering this. Otherwise I imagine you would have more similar bug reports. The FTP server is a "Snap" server and I definitely find it to be flaky, which is why I am using lftp. Perhaps it drops the connection in some particular way while I am uploading which sends lftp in an endless loop. I certainly don't think it should be using 100% CPU time. I suppose the best solution would be for me to build it with debugging and enable core dump or some such, but I too have been busy and haven't gotten around to that. I may have time for it at some point. |
