Crash with Solr on CentOS 7.4

[Ere Maijala]

Hello,

I've been testing Solr with Shenandoah using the OpenJDK version that 
ships with CentOS 7.4 (8.0_151-b12), and so far it has been promising. 
Now one node, however, crashed with SIGSEGV. So, I'd like to start with 
a couple of questions:

1. Should I switch to a more recent Java build if there are fixes 
available, and what would you recommend? I think I need a Java 8 build 
for Solr 6.6.

2. Would the hs_err*.log for the crash be of any use? I can send it if 
needed.

3. Am I in the right place to ask these questions?

Thanks,
Ere
