I've identified some SERIOUS I/O issues in the 70.7 Rhel5 kernel. If I run a moderately-loaded VE on the server, and cat a large SQL file into MySQL to create a new database in another VE, the first VE essentially blocks all disk I/O.
I had this problem before while running my nightly backups but it never got resolved. However I think this is much more serious as it means one VE can bring down another. I happened to be able to run a test between this kernel and the same machine/ve combination running the 68.5 kernel and 68.5 doesn't exhibit this problem. However, 68.5 has other problems.
Any recommendations for a kernel that doesn't have I/O problems? Anyone using the testing kernels in a production environment? Anyone else having this problem?
