 While waiting for OOM in #19249 I encountered this

 The code is
 [https://gitweb.torproject.org/onionoo.git/tree/src/main/java/org/torproject/onionoo/docs/WeightsStatus.java#n70
 here]:
 {{{
    double[] weights = new double[] { -1.0,
             Double.parseDouble(parts[5]),
             Double.parseDouble(parts[6]),
             Double.parseDouble(parts[7]),
             Double.parseDouble(parts[8]), -1.0, -1.0 };
 }}}

 Might be due to the locale of the server, but should be caught and logged.

 Maybe, use this ticket to scan the code for similar things?
