[TYPO3-Solr] schedular don#t work automatically

[Frank Eichelbaum]

Hi list , after an installation on a testserver solr works great.
Now I installed solr on a livesystem with the same software. And now i have a problem. The scheduler solr-tasks start only manually.
Everytime when started automatically via cron the task is deactivated, no error and no log.Some configuration information:solr EAP 2.6
typo3 4.5.15

php 5.3.3-7
Debian 6.0
apache2.2.16
apache solr3.5

Best regards,
Frank
