We faced very strange issue with content porter import. When one of the user was performing import process, that user received message:
The process was added to the queue on the server, but wasn't started yet because other processes are running.
After approx. 1 hour, the process triggered properly and import worked properly. Did not find any useful information in log file corresponding to this issue.
In which scenario this message will be displayed and what should be done to resolve this?
