Subject: busywait hang using extracting update handler on trunk
Hi,
While using extracting update request handler on trunk to index some 20 million
records, about 1/3 theway through solr just hung, using 100% cpu. the same
post code had been successfully used with the last release solr version, so
this may be a regrssion. If it happens again I cantry to get a thread dump.
Any thoughts?
Karl
