Error: Dynamic MMap ran out of room in Debian 10
Every Linux administrator has encountered various errors in their practice. One of the common problems you might face in Debian 10 is the ‘Dynamic MMap ran out of room’ error.
Causes of the error:
- Insufficient memory for dynamic mapped memory (MMap).
- Exceeding the MMap limit.
- Programs using a large amount of dynamic memory.
How to fix the error:
The first step in resolving this issue is to increase the MMap limit in the system. To do this, execute the following commands:
sudo sysctl -w vm.max_map_count=262144
After increasing the MMap limit, restart the necessary services or applications for the changes to take effect.
If the problem has not been resolved after increasing the MMap limit, you should analyze which programs are consuming a large amount of dynamic memory and optimize their operation. You may need to install additional monitoring tools to track memory consumption.
Sometimes the cause of the error may be a lack of RAM on the server. In this case, it is recommended to add additional memory or optimize the operation of current processes.
By following these recommendations, you can effectively solve the problem with the ‘Dynamic MMap ran out of room’ error in Debian 10 and ensure the smooth operation of your system.
