Just an update on this issue, the Solr did come back after 80 min - so not sure where was it stuck. I do use RAMBuffer of 64MB and have heap size of 6G.
There is no error is Solr log and I'd it running under WARNING level so missed the INFO if there was any during that period. I'm also not running any "optimize" command. What could cause Solr to hang for 80 min? Thanks, -vivek On Fri, Apr 3, 2009 at 1:55 PM, vivek sar <vivex...@gmail.com> wrote: > Hi, > > I'm using Solr 1.4 (nightly build - 03/29/09).
