I'm using solr 5.4, i use it to save data that a web application process and then it saved to a several solr cores, this data is replicated to another solr in a different server.
My problem is that sometimes this error happens on the solr with the master cores when my web application tries to save the processed data. I already detect part of the problem, the application tries to save the data on the same but from different threads, for a temporal solution it was to delay the data saving, but eventualy the write.lock error will happen again.
I have read the documentation but i'm still lost at what should be the best on how to configure the cores.
Right now the cores have the default configuration.
