[Xen-users] Random oopsen with Xen on Ubuntu Gutsy
I've got an AMD64 machine that's exhibiting random oopses and database
corruption using 2.6.22-14 kernel from Ubuntu Gutsy and Xen
3.1.0-0ubuntu18 also from Gutsy,
Running the same database without Xen under heavy load appears to work
fine. Machine has 3G of ECC and memtest86 works fine as well. Also,
machine ran the database just fine for a year before (unfortunately
simultaneously) switching to Gutsy and Xen.
Any suggestions?
MySQL said:
The relevant bit of the logs is this:
Jan 10 23:46:26 vegguide mysqld[22376]: InnoDB: Database page corruption on
disk or a failed
Jan 10 23:46:26 vegguide mysqld[22376]: InnoDB: file read of page 1559.
Jan 10 23:46:26 vegguide mysqld[22376]: InnoDB: You may have to recover from
a backup.
