issues with synologyNAS iscsi connection dropping?

Today, my ESXI hosts (6.7) seem to be dropping connection from their iscsi connector randomly every couple of hours, and I can’t reconnect it unless I reboot the system. Anyone ever have anything happen like this, and any idea of where I can possible start troubleshooting this?

  1. This happens to me. All 4 hosts loses connectivity but not at the same time. In my case though, the hosts reconnect by themselves.

    I tried disabling space reclamation which hasn’t helped much.

    I am currently replacing my switch and configuring one of the Synology NIC for iSCSI traffic only so we shall see how that goes.

    I’ve read that this could also occur if the NAS is under too much loaf so check on that if you can.
