Hi all,
from time to time i received (in my opinion) randomly errors from production.
At the end i figured out that a Tag read failed with timeout.
In the wrapper log. i found this entry. 2 Servers are connected via Gateway Network SERVER 1 has Vision installed and reading tags from SERVER2.
Ignition Version both Servers running 8.1.44.
Both Servers running on the same VMWARE Environment and on the same host (at this time).
I will be happy if anyone can point me in the correct direction where to search 
According IT "must be a application problem"
br,
Roland
