Hi George,

Like you've noticed, we're running into the exact problem on multiple Solr machines and we're experimenting with fixes and monitoring. OracleJDK is not contraindicated for CKAN for sure and we'd love to hear your results on it about this particular problem.

In the past, I've deployed CKAN for a client on Red Hat with Oracle JDK and it worked just fine.

Hi ckan support

Just further to my email below, i noticed that demo.ckan.org<http://demo.ckan.org> seems to be returning an error right now (8:28am UTC) - this looks like it might possibly be a solr OutOfMemory error - the site seems to be presenting the same symptoms!
Cheers
George

Subject: Solr with Oracle JDK

Hi ckan support
Another quick question (i hope)...

I'm having some Solr issues - running out of heap space memory for data.qld.gov.au<http://data.qld.gov.au> and publications.qld.gov.au<http://publications.qld.gov.au>. Increasing heap space memory has been tried and the cause of the problem appears to be quite illusive.

I'm thinking of switching to OracleJDK instead of OpenJDK to see if it makes any difference.

So, is there any reason why _not_ to use OracleJDK? Just asking in case there's some known issues with doing this.

Thanks
George
