Hello all, I came about an odd issue today when I wanted to add ca. 7M documents to my Solr index: I got a SolrServerException telling me "No space left on device". I had a look at the directory Solr (and its index) is installed in and there is plenty space (~300GB). I then noticed a file named "upload_457ee97b_1385125274b__8000_00000005.tmp" had taken up all space of the machine's /tmp directory. The partition holding the /tmp directory only has around 1GB of space and this file already took nearly 800MB. I had a look at it and I realized that the file contained the data I was adding to Solr in an XML format.
Is there a possibility to change the temporary directory for this action? I use an Iterator<SolrInputDocument> with the HttpSolrServer's add(Iterator) method for performance. So I can't just do commits from time to time. Best regards, Erik
