   Thanks for prompt reply. 
   
   Yes, both management server and hypervisors are updated to 4.18.1.0.
   
   However, it doesn't seem this is the bug you mentioned.
   As per Cloudstack management server, the job for creating a new virtual

new routerVM.
   
   Here are the last messages from the management server regarding starting new 
VM:

   ```
   After this line, no activity on this job anymore (the new routerVM appears 
as "Starting").
   
   
   The hypervisor that is chosen for the routerVM doesn't have any mentions of 
its name in the agent.log:
   ```
   # grep r-27201-VM /var/log/cloudstack/agent/agent.log
   #
   ```
   It looks like the management server doesn't even send VM creation command to 
the hypervisor.
   
   The running routerVM (the one in Running state while Cloudstack is trying to 
create the second routerVM) indeed shows the lines from the bug you've 
mentioned:
   ```
   root@r-27188-VM:~# cat /var/log/cloud.log  | grep md5

   ```
   However the timestamps in the log correspond to the VPC creation time (I 
created this test VPC at 09 Oct 2023 08:39:10). 
   
   I'm still attempting to figure out the cause of the bug by removing VPC 
elements and trying to restart it. So far I have a suspicion that large amount 
of tiers (the VPC has 11 tiers) is the cause but it is yet to be confirmed. 
   
   I will post an update here with the reproduce scenario once I have it.
