Re: "swap_pager" loop?

That message is printed when a timeout appears while waiting

or the controller was dead or malfunctioning. Are you sure
that your hardware is OK, i.e. no disk errors, good cables
etc.?

so, you are not alone ;) only our server recovers after 1 or 2 minutes.
Previously it was running 6.1-STABLE, now it's 6.2-RC1 and so far so
good, but that's probably only temporary.
BTW, before we used megarc for monitoring (through nagios each 5
minutes), now amrstat each 15 minutes.
