I have got three Ubuntu servers (virtual) running in cloud, they all are sitting in the same virtual LAN and configured with similar specs. However when I run tracepath on those three hosts to a specific target host, one of them comes out with strange output saying too many hops whereas the other two can can reach the target with 2 hops.
In fact it should be the same number of hops on all of them, any ideas what could be the issue here? Does the network stack needs a restart?
Working:
root@xx-yy-zz-02:~# tracepath target.mail.com
1?: [LOCALHOST] pmtu 1500
1: 192.168.32.2 1.797ms
1: 192.168.32.2 1.694ms
2: target.mail.com 3.075ms reached
Resume: pmtu 1500 hops 2 back 2
Not working:
root@xx-yy-zz-01:/var/log# tracepath target.mail.com
1?: [LOCALHOST] pmtu 1500

Too many hops: pmtu 1500
Resume: pmtu 1500
Routing configuration looks same on both the hosts, network team points at the virtual server itself.
