A colleague in charge of administering a larger repository mentioned seeing
these errors on Friday.
I looked through the log files on a smaller set of test systems that I've been
using, and I also have them. They occur infrequently, maybe 2-3 times in a 24
hour period. The stats updates work most of the time, but it looks like every
once in a while the update fails.
I haven't been able to cause them to happen on my systems at will - they just
happen occasionally. On his system, which receives substantial traffic, he can
cause the errors by visiting an item page and rapidly clicking and re-clicking
the refresh button on the browser. I think that he was going to adjust some
solr settings to see if that fixed the error.
If I hear more about this or have a chance to investigate some more I'll let
you know. Please do the same if you find a solution!

Asunto: [Dspace-tech] Solr Service Unavailable - Statistics
After update my DSpace instance [ http://virtualbib.fgv.br/dspace ] from 1.5.2
to 1.6.0 and start to user solr statistics, I have received several erros on
dspace.log with message "Service Unavailable" about solr exception, .
Someone has seen this error?
Know how to configure the solr transacions log to see exactly waht is happening
during the solr transactions?
