Instance fails to start on restart of sever

Help / Discuss
#21

Ok, I implemented the workaround, and this is looking good so far, although obviously I am going to have to observe this a bit before marking as answer.

Things I like about this as an answer:

  1. Description of bug fits perfectly (although I’m not sure why this didn’t start much earlier, and I’m not sure I could tell you which version I updated from when I did.)
  2. Fits and explains the seemingly random pattern of “will it start or won’t it”, which I was seeing, which was something I was struggling to understand.

Things I am less sure of:

  1. Why does Jetty make the problem less prevalent? (I know, its a race condition, almost anything could affect it)

But anyway, for the moment things are looking hopeful again - thanks again for the help so far, I will report back.

It’s a pretty tricky problem, and it’s very possible that the way Jetty loads the JARS in the webapp or the way it implements its Classloader makes it less impacted.

#23

Marking the Solr race condition deadlock as the solution. I have seen no evidence of the problem since implementing the workaround, so will have to come back if it recurs!

Many thanks again @tmortagne for your guidance and help!
