Swap space leak on Clustered E450's with Solaris 8

We have noticed the following problem on nearly every one of our Sun Cluster 2.2 clusters.
Each cluster is a three node cluster, with each node being an E450 running Solaris 8. They have been running in this configuration for several years.
We have recently noticed that the swap space shrinks over time. By this, I mean that when you do a 'df -k', the total space for swap gets smaller and smaller. Eventhough Sun support doesn't believe us, we ARE NOT seeing a process USING all of the swap space, we are seeing the actual total amount
of swap space shrinking.
The swap space will eventually shrink to the point that no swapping or writing to /tmp can be done at all.
I've looked through every FAQ, manual and website that I can find on the subject, but find nothing on the shrinking swap space. Thus far Sun support has been of no help.

I will summarize after I have received replies.

Thanks,

Brian D. Smith
