Hi. I have the "got timeout" problem in network share.

Local backups: Works fine
Share tipe: CIFS - SMB
Proxmox ver: 3.4-6/102d4547
Firewall: OFF
Ping and connectivity speed of target machine: GOOD
Ping from proxmox node to target machine: GOOD

A time ago, I was working with NFS Share and ever worked ok but one day, start to giving problems... I was thinkint that changing to SMB solved the problems, but no. The problem persists.

I have a clean target directory with no other residual files or previous failed backup files inside.

Output:

More info:

It seems that the backup starts, but something occurs and drops the connection. After 31 times proxmox is unable to reconnect. What can cause this issue?

cat /var/log/syslog
