Your Kafka service, when deployed with Docker Compose, fails to start due to memory constraints. Here are the key points from the error:
There is insufficient memory for the Java Runtime Environment to continue.
: This indicates that the Java runtime environment lacks adequate memory to proceed.Native memory allocation (mmap) failed to map 1073741824 bytes for committing reserved memory.
: Native memory allocation is trying to map 1GB of memory but is unsuccessful.Increase RAM: If you're operating in a cloud environment, consider resizing your instance to have more RAM. More RAM will alleviate the memory constraints faced by Kafka.
Optimize Java Heap Size: Adjust Kafka's Java heap size settings. You can set the maximum heap size for JVM (using the -Xmx
option). Ensure that the memory allocated to Kafka is less than the total memory, leaving some breathing space for the system and other processes.
KAFKA_HEAP_OPTS="-Xmx768m -Xms256m"
Monitor Other Processes: Use tools like top
or htop
to see which processes consume significant memory. Consider if some of them can be stopped to free up memory.
Startup Order: If you have multiple services in your docker-compose file, ensure Kafka isn't starting first. Let other lower-memory consuming services start before Kafka.
