ESXi host is pingable on DNS and IP, also from other hosts.

Anyone know how i can solve this problem without a reboot?

Regards,

Thijs

Check if your /scratch parition is full on the host.  Example from my host showing 10MB of 4GB used:

~ # ls -ld /scratch
lrwxrwxrwx    1 root     root            49 Apr  4 13:59 /scratch -> /vmfs/volumes/515b4bc4-25fdffaa-d755-0017a4771002

~ # df -h | grep 515b4bc4-25fdffaa-d755-0017a4771002
vfat          4.0G  10.1M      4.0G   0% /vmfs/volumes/515b4bc4-25fdffaa-d755-0017a4771002

Partition is not full:

Interesting.  What hardware are you running ESXi 5.1 on?  What is the hardware for this NIC?  Hopefully you verified it is supported under ESXi 5.1: http://www.vmware.com/resources/compatibility/search.php

Also, run these commands to list your installed VIBs and get info on the NIC driver being used.  This may help me determine if you're using an unsupported/outdated driver:

Check info on NICs and associated driver:

# esxcli network nic list

Example from one of our HP ProLiant servers, showing be2net driver being used.  I've edited output for simplicity:

~ # esxcli network nic list
Name     Driver  Link  Speed  Duplex  MTU
-------  ------  ----  -----  ------  ----
vmnic0   be2net  Up     6000  Full    1500 
vmnic1   be2net  Up     6000  Full    1500 
vmnic10  be2net  Down      0  Half    1500 
vmnic11  be2net  Down      0  Half    1500 
vmnic12  be2net  Down      0  Half    1500 
vmnic13  be2net  Down      0  Half    1500 
vmnic2   be2net  Down      0  Half    1500 
vmnic3   be2net  Down      0  Half    1500 
vmnic4   be2net  Down      0  Half    1500 
vmnic5   be2net  Down      0  Half    1500 
vmnic6   be2net  Up     6000  Full    1500 
vmnic7   be2net  Up     6000  Full    1500 
vmnic8   be2net  Down      0  Half    1500 
vmnic9   be2net  Down      0  Half    1500 

Command to list VIBs installed.  Hopefully you're using a VMwareCertified driver that's compatible with your hardware + ESXi 5.1:

# esxcli software vib list

Example from one of our HP ProLiant servers, using a razor-thin custom ESXi 5.1 image:

On the affected ESXi host i get this:

~ # esxcli network nic list
Connect to localhost failed: Connection failure
~ # esxcli software vib list
Connect to localhost failed: Connection failure

Okay so the drivers in use then are bnx2 and e1000e, and they are VMware Certified.  And I'm not seeing a newer version of either available from VMware.  Are you configuring any specific settings for either driver?

When did you upgrade to ESXi 5.1 build 1021289?  Were you having the same issue on a prior build of ESXi 5.1?

This error is definitely of interest when running esxcli: "Connect to localhost failed: Connection failure"

This VMware KB came up in a couple different places related to that error, suggesting the hostd process has crashed or is hung:

http://kb.vmware.com/kb/1002849

In particular, I wonder if your hostd process needs to be restarted:

http://kb.vmware.com/kb/2030663

# /etc/init.d/hostd status
Also check the output to /var/log/hostd.log
Hard to know yet if the problem is as simple as hostd failing, or if the errors you're seeing related to the NIC indicate a larger problem.

Had the same and other issues (purple screens) with previous versions of ESXi 5.1.0. Upgraded to latest version on 16-03-2013.

I do not configuring any specific settings for drivers.

I've tried severals KBs but nothing seems to work (only a reboot). I have already opened a support ticket with VMware.

What SPP set are you running on your HP DL360 G7?

Bittersweet I suppose.  It's working for now, until it happens again.

I would check the firmware and BIOS configuration on the server to ensure it's supported for ESXi 5.1.

Checking HP's support matrix, your hardware is supported under ESXi 5.1:

http://h18004.www1.hp.com/products/servers/vmware/supportmatrix/hpvmware.html

However, in terms of firmware (the SPP firmware set), HP started supporting ESXi 5.1 as of SPP 2012.08.00:

http://ftp.hp.com/pub/softlib2/software1/doc/p1822529277/v81463/SPP2012.08.0rev1ReleaseNotes.pdf

You could take the easy route and just apply the latest SPP set to the server (SPP 2013.02.0):

http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=4091409&sp...

Here's all the drivers/firmware HP supports for DL360 G7 with ESXi 5.1.  I don't personally use HP selected drivers over VMware Certified drivers, but firmware and BIOS are important to keep in sync:

http://h20565.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdHome/?sp4ts.oid=4091409&spf_p...

Also would run diagnostics via HP Smart Start 8.70 to see if any hardware tests fail.  We generally run all tests (except HDD tests because they are very time consuming) for 3 - 4 days to ensure it holds up without error before deploying ESXi on the hardware.

Updated today one ESXi host with SPP 2013.02.0. Hopefully this resolve the issues.

I don't understand the cause that would do this in the first place but here is the ARTICLE from VMWare.

Link

Sorry, I guess VMware don't like to have links to their own site posted here.  Guess you will have to go hunt.

Hint:  2056181 is the Article ID in the Knowledge Base

Hi,

Do you happen to use Veeam Backup and Replication or/and with Veeam One combination?

We are using above Veeam product and we are suspecting it is the caused of this issue

As I see you are getting events >>>failed with error No buffer space available (55)<<<< This could be that few applications might have failed to close TCP sockets. Have tried to reboot your host.

Do check this too VMware KB: ESXi 5.1 host is disconnected in vCenter Server and reports the error:No buffer space ava...

I highly believe the application in our case is Veeam One or/and Veeam Backup and Replication

Now to the question why would this causes ESXi to be unstable? Does it mean ESXi 5.1 host is easily subjected to DOS attacks?

Hi,

All issues are gone after using HP Service Pack for ProLiant (SPP).
