Re: track_file function ?

Hello again Quentin,

So far this is the only issue I have with latest beta:
Feb  1 15:32:56 bz-perflab-6-vr Keepalived_vrrp[10486]: (4137): Success creating VMAC interface vrrp4.137.1
Feb  1 15:32:56 bz-perflab-6-vr Keepalived_vrrp[10486]: Netlink: Received message overrun - (No buffer space available)

This results in:
+----------+-------------+-----------------------------+---------+----------+-------------+---------+----------------------------+
| Instance |  Interface  |          Addresses          | Version | Priority | Master prio |  State  |      Last Transition       |
+----------+-------------+-----------------------------+---------+----------+-------------+---------+----------------------------+
|   4137   | vrrp4.137.1 |         10.0.137.254        |    2    |   100    |      0      | Unknown | 2018-02-01 15:32:57.263674 |

Is there any chance we can set a very short delay (few milliseconds) between each interface creation ?

Regards,
