Same issue just started happening for me with one server running vSohere and previous post appears to have resolved… Thanks

I had the same problem with 4 ESX servers using v-center. one server keep disconnecting.

The way it solved is by connecting to the ESX server which has the problem using putty

and ran
/etc/init.d/vmware-vpxa stop
/etc/init.d/vmware-vpxa start

We have this problem on a brand new ESX 4.0 server and VC 4.0.
My server disconnects every few minutes. While it was in test with no load it worked flawlessly, but as soon as I Vmotioned my VMs to it it started disconnecting. Opening a support case for that SOAP patch now

I hear there is a patch for this problem. I is cuased by SOAP timeouts. You need to open a service request with VMware to get it. I can’t becuase I get my support through HP and I figured there would be a new vCenter released before I could get a patch through them. Now if someone was to get the patch from VMware support and send it to me I would gladly test it for them.

You’d think that the QA testing would catch stuff like that. If the problem really does stem from something as mundane as SPI firewalls, that’s pretty bad since many people can be expected to be using those. Can’t wait to see what VI4 has in store bug-wise!

I too have been struggling with this problem since U3. I’m now try VC U4 and I am still having it. I am using a Cisco ASA as my firewall. Per another posting I add this line to my configuration yesterday.
sysopt connection tcpmss 0
Today I added the dummys, but I still get the error. I have noticed each thing I try seems to help a little, but the problem will never go away.

Having this problem on a ’solo’ upd 3 box, which is outside of virtual centre (our test env box, with out a licenses for vc!) i.e. direct vi session to the host
It keeps dropping out my VI sessions… Argh! No VC, so no scheduled task… Any ideas on a work around? Perhaps a cronjob on the host?

Hi Richard

Just to let you know that the workaround has resolved the issue with the consistent failure we were having. Will keep an eye out for the permanent fix from VMware.

Thanks

Have set this up so will let you know how we get on. we will know quite quickly if it’s working as we have certain tasks that happen daily that are consistently erroring.

C Stewart,
I don’t know the answer to that for sure, but to me it only would make sense to do this on the affected hosts.

for your workaround, does the dummy VM have to be created on every host or just the host that your having problems with. Only one of our hosts is having this issue, funnily enough its the only one that has firewalls between it and the vCenter Server

I have had this problem for ages! This specific cause might be U3 related but I am running U2 and have opened at least five support cases about this.

It is always some “Unknown environmental cause” and I have to close them because I just don’t have time to run network traces all over north america.

Any other ideas on what might cause this kind of behavior?
