Swap memory full

retechpro
Hi All, my swap memory is reached to 99%. Swap Size is 4gb which has been reached. my server specs is 16 core with 128gb ram. Currently half of the Ram is free. Is it good to increase the swap memory? Or i can refresh the existing memory. anyone can help.

    Hey there! It really depends on the resources being used on the system. It would be best to evaluate what is causing so much swap to be used, and then you would be able to decide if increasing it will help the situation, or just lead to a bigger swap area getting full again. If you are only using 50% of your RAM, is seems odd to me that swap would be completely full already. Since this area isn't controlled by cPanel, you may need to reach out to your host to confirm the hardware is working properly on the system.

    How can i verify why limit has been reached. Also how can i decrease now as it has been full. which thing i need to verify to my server provider related to hardware.

    Linux systems usually use swap before the RAM memory is full. This will tell what is the swappiness parameter: cat /proc/sys/vm/swappiness

    swappiness value 10 means that swap will be used when RAM is 90% full. That would indicate that in some point more than 90% of memory has been used. I found instructions how to clear swap:
