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:
The vmkernel.log warning is addressed at this KB including a solution/workaround.
Maybe this will fit your situation.
Best regards
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.
