Intelligent idea of ​​freezing at startup, fsnotifier64 uses RAM 6.5G

Question

I use fedora 21, when I start Intellij, it freezes my mouse and keyboard by about 75%, but somehow it continues to load while the input is frozen. When he left, I was happy, but now my fsnotifier64 process uses 6.5 GB of RAM. I changed my vmoptions, which doesn’t change anything. What would you advise me to try to fix this problem.
