Solr and big synonym file

I have a big synonym dictionary and I created a file correctly formated to use it with solr. This file has a size of 4mb. But when I want to start solr using Tomcat, solr is blocke开发者_运维百科d in start.

What is the problem ? The file is too big ?

Thanks.

we created a new synonymsfilter to address this problem, the old synonymsfilter was quite bad with such large synonyms files:

Unless something changes, should make it into 3.4

I think it has nothing to do with tomcat memory, try increasing solr memory. Found this link which mentions that synonym.txt will take lot of heap space, so mostly its due to solr running out of memory
