wrong data?

[crystalbit]

Hello

by free((err, info) => console.log(info)) I get

{ mem:
 { total: 2090212,
 used: 882528,
 free: 810120,
 shared: 408,
 buffers: 397564,
 cached: 1096208,
 usable: 2303892 },
swap: { total: 0, used: 0, free: 0 },
cache: { used: -213680, free: 2303892 },
buffer: { used: -213680, free: 2303892 } }

while

free -m
              total        used        free      shared  buff/cache   available
Mem:           2041         832         820           0         388        1099
Swap:             0           0           0

Something is wrong: usable memory is over total; used cache and buffer are negative
