Bug#582605: INFO: task * blocked for more than 120 seconds
Package: linux-2.6
Followup-For: Bug #582605
The last few months I'm getting these messages at more or less random
intervals (every few days or so) concerning different tasks (not only cron). During the time
of this soft lockup the server remains unresponsive for a few minutes to
continue as normal afterwards. No SSH, HTTP or any other connection is
possible during that time. I have found a few reports concerning this matter
(such as #582605) but I'm unaware whether this is this same problem as I'm
having. Does anyone know a solution for this?
Thanks
