The Grid Engine accounting logs showed 3722 restarts for https://tools.wmflabs.org/?tool=para. $HOME/error.log was full of messages like this:
2017-06-27 23:20:29: (log.c.166) server started 2017-06-27 23:20:29: (mod_fastcgi.c.1103) the fastcgi-backend /data/project/para/public_html/test.fcgi failed to start: 2017-06-27 23:20:29: (mod_fastcgi.c.1107) child exited with status 2 /data/project/para/public_html/test.fcgi 2017-06-27 23:20:29: (mod_fastcgi.c.1110) If you're trying to run your app as a FastCGI backend, make sure you're using the FastCGI-enabled version. If this is PHP on Gentoo, add 'fastcgi' to the USE flags. 2017-06-27 23:20:29: (mod_fastcgi.c.1398) [ERROR]: spawning fcgi failed. 2017-06-27 23:20:29: (server.c.1021) Configuration of plugins failed. Going down.
Seems to be caused by this snippet of $HOME/.lighttpd.conf:
fastcgi.server += ( "test.fcgi" => ( "test" => ( "bin-path" => "/data/project/para/public_html/test.fcgi", "socket" => "/tmp/socket.para.test.fcgi" )) )
There is no /data/project/para/public_html/test.fcgi file.
I have stopped the webservice until @Para can fix the lighttpd config.
