swap_pager_getswapspace: failed

[Spidey Knepscheld]

Hi Guys
 
I am running FreeBSD & Exim as MTA on the same server I run Squid as a
transperent proxy.The server is running very slow.I do have a type of
DoS at moment.My server admin is on holiday.Amavis and the Virus
Scanners seem to have stoped working so MyDoom & Netsky and what ever
you can imagine is loose on the network.I get the following error on the
monitor continiously : swap_pager_getswapspace: failed
 
I hope anyone can help
