On Linux guest operating systems communication between the agent and scheduler can be delayed if there isn't sufficient entropy available. One can verify the level of entropy available by executing the command below. A reading of > 2000 is recommended for normal operation of the agent.
Steps to identify the problem:
The agent's transmitter log with log level set to 8 is required to identify the problem. If there are any delays (than normal operation) between lines 'Socket factory has been obtained' and 'Communication protocol has been created', these delays might be due to low entropy levels.

Increase the entropy level available to the system.
One Red Hat based systems one can use rng-tools with --rng-device=
There are other hardware based solutions available as well, consult your Unix administrator prior to implementing the above solution.
