vCenter vsphere-client service fails with Java memory error

[andreir]

Hi all,

on the latest vCenter appliance 6.0u3, the vsphere-client failos periodically with java memory errors, causing all web client connections to hang until "service vsphere-client restart" command can be issued manually. Any idea how to raise the Java server memory on VCSA?

There must be a memory leak in vsphere-client - I bumped the memory to 5 GB using "cloudvm-ram-size -C 5120 vsphere-client" command and the client still hangs after a couple of hours.

I have the exact same issue on 6.0 U3.

Did you find a resolution in the end andreir​?

[andreir]

Unfortunately I was unable to resolve it with 6.0 version. I had a lot of third-party plugins in the vCenter (this was a lab), I suspect one was leaking memory. My solution was to upgrade to 6.5.

I suspected as much.. onwards to 6.5! - thanks
