[TYPO3-Solr] Records disappear after a given time

[Kevin von Spiczak]

Hi,

my problem is, that the solr index gets cleared automatically after a given time (2,3 days).
I can't really reproduce this issue or understand what is going on behind the scenes.
We have a cronjob set up to reindex the page automatically, but from time to time the already indexed pages get deleted from the solr records.

Any information about this?

Kevin
