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


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..

There was no module loaded, and unfortunlately, I cannot find the System.map or /proc/ksyms file for the affected kernel!
Anyway thank you for your explanation. I have upgraded the kernel to 2.6.17.14 and wish that it can fix the problem. Thank you

Kyle
