[TYPO3-Solr] Commit Solr Index scheduler task failing with 503 error

[Bernhard Karimi]

Hi,

there is a bug report (http://forge.typo3.org/issues/48297) that
describes pretty much an error I have:

"When invoking the "Commit Solr Index" scheduler task (cronjob or even
manually) it fails with the following message:
Execution of task "Commit Solr Index (solr)" failed with the following
message: Solr response does not appear to be valid JSON, please examine
the raw response with getRawResponse() method"

Unfortunately there is no reaction so far. Has anybody a solution or at
least an idea?

Another strange thing:
We updated solr from 3.6.0 to 3.6.2, but typo3 does not recognize this
change and still sticks in the reports module to the old solr 3.6.0
version.
Why?

Thanks in advance,
Bernhard
