Hi,
Recently my mysql servershows something like:
Dec 18 18:24:05 sql kernel: schedule_timeout: wrong timeout value
ffffffff from c0284efd
Dec 18 18:24:36 sql last message repeated 19939 times
Dec 18 18:25:37 sql last message repeated 33392 times
from syslog every 1 or 2 days. Whenever the messages show, mysql server
stop accept new connections from the same network, and I need to restart
the mysql service and then it will keep running well for 1-2 days until
the messages show up again.
The server has been running over 1 year without any problem, the problem
started show up around 2 weeks ago. It's running kernel 2.6.12, and
mysql server, nothing else. Hardware is Pentium 4 2.8GHz with
hyperthreading enabled.
What does the kernel message mean and why it make mysql stop accept new
connections? Is it hardware problem or try upgrade the kernel may help?
Please CC me if possible. Thank you
The message means some code in the kernel or in some module passed a
negative value to schedule_timeout which it shouldn't have. The c0284efd
value is the address of the function that made the call - you may be
able to look that up in your /proc/ksyms or the System.map file and
figure out what function that is..
