Thanks, much appreciated!

I think after a crash it's mostly to use dumps there (we have several from the recent pas)
but I'm not sure they will help, and it takes time to analyse.

In the past I took the time to analyse some of them and it was interesting. For instance in
2010 I found a bug in a Java version we were using and it 
helped me in a custom project I was also doing then: https://markmail.org/message/byu2ivjn7wckayzz

Lastly it was mostly lack of memory, despite having 8GB now. I created https://issues.apache.org/jira/browse/INFRA-16780
for that, but not sure it was 
the reason. At least we have less issues since.

Before (months ago) the Infra was monitoring our demos and alerting us by mail (you just had
to subscribe). Unfortunately we are on our own for that 
now, too much projects in the ASF...
As as I said initially in this thread I'm currently using montastic.com for the email alerts.
My idea when I started this thread was that it all depends on me, and that's bad. So I wanted
people to be aware, you are much welcome.
