ESXI 6.5 Failed - Transport (VMDB) error -45: Failed to connect to peer process.

Jump to solution

Hey,

 

Im running 6.5.0 (Build 4887370) with a few VMs. Today one of the VMs locked up but so i rebooted it from the webUI and i got the following error.

 

 

ESXI 6.5  Failed - Transport (VMDB) error -45: Failed to connect to peer process.

 

 

 

I rebooted the host and now all VMs are not starting and giving me that error. I did some digging and it found this issue is related to not enough memory but I appear to have plently of memory on the datastore.

 

 

 

 df -h
Filesystem   Size   Used Available Use% Mounted on
VMFS-5     924.0G 714.5G    209.5G  77% /vmfs/volumes/ds

I tired to create a files on the datastore and i get an Input/output error. I can delete files from the data store but not create them.

I checked the logs on the host and found the following

 

==> /var/log/vmkwarning.log <==

The host also appears to have plenty of inodes so that should not be the problem.

stat -f /
  File: "/"

Inodes: Total: 655360     Free: 649192

 

anyone have any ideas what the cause could be there were no changes made to this Host in months so im not sure whats going on?
