...
The first error has more chances to point to the real root cause of the issue.

app/{vminsert,vmstorage}: wait for ack from vmstorage after each packet sent to it from vminsert
...
This should protect from possible data loss when `vmstorage` is stopped while the packet is sent from `vminsert`.
This commit switches to new protocol between vminsert and vmstorage, which is incompatible
with the previous protocol. So it is required that both vminsert and vmstorage nodes are updated.

lib/{storage,mergeset}: use time.Ticker instead of time.Timer where appropriate
...
It has been appeared that time.Timer was used in places where time.Ticker must be used instead.
This could result in blocked goroutines as in the https://github.com/VictoriaMetrics/VictoriaMetrics/issues/316 .

app/vminsert/netstorage: increase timeout for pushing data from vminsert to vmstorage by 3x
...
Our clients report that the previous timeout could lead to frequent errors when
vmstorage starts background merge for big parts on slow HDD.

app/vminsert/netstorage: make sure the conn exists before closing it in storageNode.closeBrokenConn
...
The conn can be missing or already closed during the call to storageNode.closeBrokenConn.
Prevent `nil pointer dereference` panic by verifying whether the conn is already closed.
Thanks to @CH-anhngo for reporting the issue.

app/vminsert: improve handling of unhealthy vmstorage nodes
...
* Spread load evenly among remaining healthy nodes instead of hammering
the next node after the unhealthy node.
* Make sure that the packet is flushed to storage node before returning success.
Previously packets could stay in local buffers and thus lost on connection errors.
* Keep rows in the limited memory when all the storage nodes are unhealthy.
