I moved from a Solaris server to a Linux one and my search is broken.

If I create new topics I can search those ok.

I have reindexed to death.

After reindexing there are files in cachesearch_indexforum1index1.cgi that are 0 bytes.

Strange thing is these never existed on the old server. Same software same config.

Also on the old server I could delete the cache and it would rebuild it. Now if I delete it, it complains directory search_index is missing from cache.

Version 6.7.2
