Solr client 'Timeout was reached' ~ when new documents are inserted and commits are made.

[Rafał Radecki]

Hi All. 

I have a solr 3.5 multicore installation. It has ~2500000 of documents, ~1,5GB 
of index data. 
When the solr is feed with new documents I see for a few seconds timeouts 
'Timeout was reached' on clients. 
Is it normal behaviour of solr during inserting of new documents? 

Best regards,
