There are some issues which more experienced folks than I pointed out to
me on this list.  We are required to use newer kernels (I believe >=.26)
because of a serious bug in iSCSI in earlier kernels.  However, in
both .27 and .28, we have picked up an extremely serious bug that has me
eagerly awaiting stable vserver for .29.  Every once and a while, a
process sends the CPU into some kind of loop.  The process cannot be
killed.  The only option is a reboot of the vserver host, not the
individual vserver.  We saw this regularly with the OSSEC rootkit
product but it is not specific to OSSEC; we did see one other non-OSSEC
instance - John
