With the help from Stoyan Zhekov, we identified and fixed a bug that may
cause 503 error in ruby-lsapi 1.7-1.9 release.
Please upgrade to ruby-lsapi 1.10 as early as possible if you are using
ruby-lsapi 1.7-1.9.
The latest package is available through ruby gem now, please make sure
to uninstall earlier release.
My sincere apology if the bug causes any trouble for you.
