Hi,

try to restart the management services using the DCUI or through SSH -> "services.sh restart"

It also restarts the service responsible for the communication between the host and vCenter.

Afterwards try to reconnect the server at the vCenter

Best regards

I tried to restart the problematic ESXi server before, but another server would interrupt the connection with vCenter server.

I want to know the cause of the problem and how to avoid it?

Hi there,

could you take a look at this KB:

VMware Knowledge Base

The vmkernel.log warning is addressed at this KB including a solution/workaround.

Maybe this will fit your situation.

This is issue noticed in ESXi with Cisco Nexus 1000V Switch (version 4.2(1)SV2(2.1))

VEM loses network conectivity with PLFMESX_NO_MEMORY l2CommonWrite message (CSCvb72554)

Symptom:

VEM loses network connectivity suddenly.

The following messages are shown in vmkernel logs.

PLFMESX_VMW_ERR sf_platform_packet_alloc: cannot alloc new pkt

PLFMESX_VMW_ERR Packet Copy Failed

PLFMESX_NO_MEMORY l2CommonWrite: Failed to alloc pkt

Conditions:

Nexus1000V 4.2(1)SV2(2.1)

Workaround:

Not found for now.

Restarting a server will clear this problem.

If you found my answers helpful please consider marking them as helpful or correct.
