[3671] 10 Sep 13:59:53.821 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
[3671] 10 Sep 13:59:53.822 # Redis can't set maximum open files to 10032 because of OS error: Operation not permitted.
[3671] 10 Sep 13:59:53.823 # Current maximum open files is 1024. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.
