问题 I installed grakn 1.0.0 on debian/wheezy with jdk8 while starting grakn server it says STORAGE .... STARTED QUEUE ..... FAILED I found nothing useful in the log directory. any clues where I could look or where I could ask will be appreciated thanks, Gerald 回答1: I had the same problem. After failing to start, it created a file (like hs_err_pid20005.log) that said: # There is insufficient memory for the Java Runtime Environment to continue. # Native memory allocation (mmap) failed to map
