2021-10-07 10:17:05 -0500 marked best answer roslibjs does not receive message containing sensor_msgs/CompressedImage field

I tried to create the custom message encapsulating several sensor_msgs/CompressedImage fields. I planned to connect it with roslibjs to display the images on the webpage. But the web application does not receive anything. Actually, I cannot even to catch the message receiving event. The message type is set up correctly. The publisher is saying the following:

[WARN] [1633447998.427242]: Inbound TCP/IP connection failed: connection from sender terminated before handshake header received. 0 bytes were received. Please check sender for additional details

Message structure:

Header header
sensor_msgs/CompressedImage raw_frame
sensor_msgs/CompressedImage annotated_frame
sensor_msgs/CompressedImage depth_map
bool has_detections
roi[] detections

where roi is another custom message. When I am trying to pass just sensor_msgs/CompressedImage everything works. Could you please help me to investigate why?

We experienced strange behaviour on our embedded SPARC-like system. Just after start, the rosout process loads CPU on 100%. We would be very appreciated if you guys help us to reveal the reason of such behaviour.

Also, how many processes should roscore run?
