Internal error in SearchEngine trying to make WikiSearcher: null
I'm encountering a strange error msg today. It's working fine before, it started just after I restarted the server.
Following is the log from the server. [pool-2-thread-13] ERROR org.wikimedia.lsearch.search.SearchEngine - Internal error in SearchEngine trying to make WikiSearcher: null
On Browser I got: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Error: 500 Server error</title> </head> <body>
500 Server error
LSearch daemon on localhost
</body> </html>
I'll really appreciate if you can help me to understand the error. Thanks in advance,
sincerely yours Babur
