I rolled a new kernel that’s identical to the stock CentOS 2.6.32-220.el6 kernel with the exception of the new idmapper being enabled. Unfortunately there’s been no improvement.
Did you get a chance to try the RHEL kernel?
Hope to get it installed this weekend.
FYI have been running 2.6.32-251.el6.x86_64 all weekend and thus far my
issues appear to have fixed.
