sxmkindex crashing
Posted: Fri Jun 22, 2007 5:34 am
Hello I'm having a problem with sxmkindex. Every time I try to run sxmkindex it crashes after a couple of users. It also crashes for some users when I run it with a user name. I get this entry in the log:
I straced it and got this:
It crashes right after issuing a request to tomcat and reading the results. I checked the tomcat logs and found this:
Tomcat is throwing an exception. I found the request sxmkindex was making in apache logs and tried it myself with wget. I got back:
Without looking at sxmkindex source code I'm guessing that it is trying to parse the results from the request and it is chocking on the last line "Failed to get searcher" because the format is wrong?
I started getting this problem when I was on 11.0.3 and changed lucene configuration according to bug 15242. Now I'm on 11.1.0 with the default config (which is almost the same with the one in the bug) and I'm still having the same problem. I have run omscan -Aavfx several times and have done omtidyallu -M with no result. It's not a big problem for me because searching is not affected (I think!) but I would like to see it solved.
