We recently did a Content Database refresh in our Test environment and am now finding that Search is not working. We are using Sharepoint 2010 Search Server and all has been running fine until the latest refresh and now the Search is failing with the error message:
The filter daemon did not respond within the timeout limit.
Nothing has changed that I can find, accounts and permissions are all the same and have not changed. The sts4 site is found and crawled but not the http site, in content sources I have the http site set up, and this worked until the latest refresh. In some ways, because the content database is so large, I am wondering if maybe the size is an issue and that is slowing down the crawl somehow.
