Daniel, There is a note on Metalink saying this error could be related to /proc/sys/fs/aio-max-nr. If you have not tuned this parameter, try increasing it to 1048576, or more if needed. You will have to look on /proc/sys/fs/aio-nr to see if you are hitting the current limit.

I know that this kernel paramater is no longer tunable in 2.6 kernels. I have a dozen or so databases on another filesystems and on other machines, none of which exhibit this behavior. Does anyone know why it complains of an 'interrupted system call' and I/O limits for this filesystem and/or if they pose a problem? Kernel is 2.6.18-53.el5 #1 SMP Wed Oct 10 16:34:19 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux Under Red Hat v5.1 with ocfs2-2.6.18-53.el5-1.2.8-2.el5.
