Thanks Stefan! I executed the SHOW PROCESSLIST; command. (Is it what you mean? I've never tried it before...) It seems that when I executed one delta-import command, several threads were inserted into the table and removed after commit. Also it looks like the number of threads are pretty much equal to the number of entity in my db-data-config.xml.
So, if the number of threads in the process list is larger than max_connections, I would get the "too many connections" error. Am I thinking the right way? If it is right, maybe I should think of the commit timing, changing the number of max_connections, and/or some other ways... If there are any other idea, please let me know =) Thanks a lot! -- View this message in context: http://lucene.472066.n3.nabble.com/DIH-Exception-with-Too-many-connections-tp3005213p3005401.html Sent from the Solr - User mailing list archive at Nabble.com.
