search.conf paramter max_indexing_buffer_size doesn't seem to work
We are using CA 1.7.9. We've got a big collection of 20.000 objects and are using sql search for it.
By rebuilding the search index with CaUtils we experienced an error "PHP Fatal error: Allowed memory size of XXXXXX bytes exhausted". We tried to extend the memory by ini_set('memory_limit', '8000M'), and that worked well for a while, but our collection has grown and still is.
It seems that the max_indexing_buffer_size parameter in search.conf is not taken. We can't see any difference while rebuilding the search index.
Rebuilding the search index of the tables one by one helped. But some strange stuff is going on after doing that and we had major issues with searching.
Is there a better way to safe memory while rebuilding the search index?
