While running a "yum upgrade" with around 200MB of updates, the system became significantly slow (3 seconds for Chrome to scroll down after hitting space bar!) and I noticed in /var/log/messages Nov 26 22:12:08 localhost kernel: no space left, need 61440, 18579456 delalloc bytes, 10387451904 bytes_used, 0 bytes_reserved, 0 bytes_pinned, 0 bytes_read only, 0 may use 10406068224 total Although "df -h" shows 16G of free space for the root fs. I thought I'd report this. Let me know if you want more diagnostics. Regards ^ permalink raw reply [flat|nested] 4+ messages in thread
