Can you try the --no-chunk-listing option:

./vertical backup jira.bob.io --no-chunk-listing

This is to avoid listing the existing chunks on the storage to save some memory.

I tried with --no-chunk-listing and its still the same error.

Uploading file jira.bob.io-flat.vmdk

I am using ESXi 6.5.0 Update 1 (Build 5969303)

is there any commands i can use to free up memory in the esxi host? I tried a reboot and there was no change in the error.

thanks for the help

Can you run this command on a different ssh terminal while Vertical Backup is running:

esxcfg-info | grep -A100 vertical  | grep MB

This will tell the memory usage and the maximum amount allowed by ESXi.

It doesn't look like a out-of-memory issue.

I notice that a new snapshot wasn't created before reading that vmdk file. Here is sample output on my ESXi:

What is missing from your output is the line Creating a new virtual machine snapshot for....

Did you accidentally remove that line when pasting it here?

If a new snapshot isn't created, then that vmdk file should not be readable, although I had no clue why a memory error was returned.
