stops after indexing 50 sites

[BulForce]

I have messed up something and now the spider stops after indexing 50 sites.

I use command line indexing

#php -f spider.php sites.txt >> sites.log

All was fine, but i have edited something and now the spider stops after the 50th site.

can anyone help me?

Look at your config file and compare the settings to the documentation to see what values have changed.

I look at conf and docs many hours nothing solved the problem.
And i decide to upgrade from 1.8.3 to 1.8.7 and this solved my problem :)
