SharePoint Foundation 2010: search error: "Your search cannot be completed because of a service error."

Hi,

I have SharePoint Foundation 2010 running on a single server with databases, with a second server in the farm serving as a 2nd app tier. Both server have the exact same versions of SharePoint loaded (according to the Central Admin site).

Whenever I try to run a search from any site in my SharePoint Foundation 2010 installation (in this example I typed "this is my query"), it hangs for 20-30 seconds while the IE status bar says:

Waiting for http://SERVER2010:80/tfs/SITE1/_layouts/searchresults.aspx?k=this%20is%20my%20query&u=http%3A%2F%2Ftfs2010db%2Ftfs%2FSITE1

Then it finally returns a results screen with an error that says: "Your search cannot be completed because of a service error. Try your search again or contact your administrator for more information."

Checking the SharePoint logs under C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS, the relevant entries say the following (items I deem importantbolded):

Not sure what "resource limit is reached" actually means. This SharePoint installation is running under regular SQL 2008 R2, and theWSS_Content database is fairly small (10gig). I've reviewed the Search Service, the process account running it, theWSS_SEARCH index database, and verified that the Content database is using the proper index database. Everything looks like it should be crawling/indexing/working fine. But the WSS_SEARCHdatabase isn't very large, so I'm not sure if the crawling is actually filling it with anything.

Not sure where to start seriously troubleshooting this. Any advice would be appreciated. Thanks.
