{"error":"Cannot read property '_csrf' of undefined"}



  • I need help....





  • @Lingyong-Zhang, check the output of /var/log/redis/redis.log (although your redis log may be in a different location):

    sudo cat /var/log/redis/redis.log
    

    It will likely contain an error message about either maxconnections or vm.overcommit. In the case of the former, lower the max connections in /etc/redis.conf to whatever ulimit -n gives you. In the case of the latter, you have to allow overcommitting of memory:

    sudo su && echo 1 > /proc/sys/vm/overcommit_memory
    

    See the FAQ for more info.

    Last, make sure you restart Redis after you make both of these changes:

    sudo service redis restart
    


  • @Guiri Yes, use the redis cost so much memery.
    I checked the log, it says:

  • @Guiri I see, I have solved.
    But I have some problems, I don't know which database I should use.
    mongo or redis ?
