Bug#703296: apt-cacher-ng: Sometimes eats 100% CPU forever without apparent activity or reason
Hi! acng isn't eating 100% CPU on me right now, but it is eating about 10% CPU. I've attached an strace as suggested -- I let it run for a couple of seconds and it generated a very large log which doesn't (at first glance) look interesting at all. I also increased the verbosity but nothing is output to the logs at all during this idle period. Restarting acng is enough to get it back to a normal amount of CPU usage and strace on that just gives: Process 10289 attached - interrupt to quit select(8, [5 6 7], [], NULL, NULL^C unfinished ... Process 10289 detached Hope this is in some way enlightening! cheers Stuart -- Stuart Prescotthttp://www.nanonanonano.net/ stu...@nanonanonano.net Debian Developer http://www.debian.org/ stu...@debian.org GPG fingerprintBE65 FD1E F4EA 08F3 23D4 3C6D 9FE8 B8CD 71C5 D1A8 GPG fingerprint90E2 D2C1 AD14 6A1B 7EBB 891D BBC1 7EBB 1396 F2F7 acng-strace-log.txt.xz Description: application/xz
Bug#703296: apt-cacher-ng: Sometimes eats 100% CPU forever without apparent activity or reason
Package: apt-cacher-ng Version: 0.7.11-1 Severity: important Hi, on a few Wheezy systems I run, apt-cacher-ng from sid often starts eating 100% of the CPU and seems to never stop, unless I restart it. I've no idea what triggered this, but at least the CPU eating goes on even if there is no activity reported in the apt-cacher-ng logs.

Bug#703296: apt-cacher-ng: Sometimes eats 100% CPU forever without apparent activity or reason
Hallo, * intrig...@debian.org [Sun, Mar 17 2013, 07:46:57PM]: on a few Wheezy systems I run, apt-cacher-ng from sid often starts eating 100% of the CPU and seems to never stop, unless I restart it. I've no idea what triggered this, but at least the CPU eating goes on even if there is no activity reported in the apt-cacher-ng logs. Please enable more verbosity, i.e. Debug:7 in acng.conf. It might be the daily cleanup job that triggers it but we need to know more. If you can catch it, please monitor its activies for a while, i.e. strace -f -p $(pidof apt-cacher-ng) | tee strace-log.txt Thanks, Eduard. -- Getty Linux Systeme sind da mehr wie Maenner, die reifen mit der Zeit, sind aber am anfang eigentlich zu garnix zu gebrauchen -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
