Can't invalidate cache for default.site (TeamSite 6.7.2 SP2)

System

TeamSite 6.7.2 SP2
LiveSite 3.1.0.2
Solaris 9

Hi folks,

After applying SP2 to our 6.7.2 environment, we can no longer invalidate runtime cache on the default.site file.

Here's how to reproduce the issue:

1) In CCPro, select "default.site"
2) Choose "SitePublisher --> Invalidate Runtime Cache" from the menu
3) The following error pops up: Command iw.livesite.ccpro.cache_invalidation cannot be handled

I have attached two screenshots to help demonstrate the steps above.

The ONLY log entry that appears is a "500" error in access.log (i.e., general server-side error). There's nothing about this in the servletd_out.log.

Invalidating cache for individual .page files works fine. This issue seems to be only with default.site

Has anyone else on 6.7.2 SP2 experienced this issue?

Thanks in advance,
