[TYPO3] Crawler and errors in logs

[Sylvain Gourvil]

HI all

I am going to be mad about indexed_search and site_crawler.

I have configured the indexing_configuration element and my cron is 
workin well.

But in crawler log, I have this  : "Error: 
a:4:{s:7:"running";b:1;s:10:"parameters";a:2:{..." on each page.

How could I know what is the issue with such serialized label. Where 
could I find the total erro message ?

Thanks in advance.
