| Description |
|
If the server id is larger than the maximum positive value of a 32-bit integer, there will be an overflow inside MaxScale. The server id should be 64-bit everywhere. |

Good find. The server id is actually 32bits, but unsigned (0-2^32 - 1). The monitor used an int and parsed with the atoi(), causing numbers > 2^31 to appear negative. In any case, now a 64bit int is used to allow -1 as special value. |
