I upgraded from gentoo-sources-2.6.27-r4 to -r5 a couple of days ago and |
| 2 |
got the below error messages in /var/log/messages. Also dovecot was |
| 3 |
using 100% CPU and could not be killed. This resulted in me having to |
| 4 |
hard reset the server. This happened 3 times until I eventually reverted |
| 5 |
back to -r4 and all was stable again. The config used for both kernels |
| 6 |
was the same and it happened after irregular intervals of between 5 |
| 7 |
hours and 9 hours. |
| 8 |
|
| 9 |
Anyone have any ideas? Things are back to normal now but I will |
| 10 |
obviously be wary about my next kernel upgrade. |

Cheers, |

Dave. |
