Hi,
We are using zabbix for half a year.
Recently we got an issue need help.
We have 600 virtual machine which is using centos 6.5, in ESX 6.0?
We have 3 times got a very large data of network outgoing of eth0.
1)The agent and the virtual machine didn't restart.
2)3 times happen in different virtual machines in different physical machines.
3)No error log in system and zabbix log.
4)Every agent has different name, it is not cause by 2 agents use the same name.

Do you met this issue before?Or have any suggestion?

Thanks
LiXiang

Error data of one time. time interval is 20S.
We can see we lost one time after this large data, I know it is because next time data is less than the large data, so drop it.
Read /proc/net/dev, get the data is 797236927897.
