Welcome to the forums, @srikar!

This question is answered here:

Safe to remove old core files?

Hello, I am using memSQL v6, and found many core files such as: /data/memsql/core.xxx Based on documentation seems this are are full core dumps files that are produced upon a crash. Now, after a few months this core.xxx files are taking a lot of disk storage space, I believe they are only useful for recovering data after a crash, therefore it is safe to delete old core.xxx files? Thanks, Santiago

@srikar,

Note that core files are generated, if something caused the database engine to crash. They hold information on what caused the problem, which can be investigated with gdb. These files you indicated are over a year old. However, if you notice new core files getting generated, you likely want to look into why that is occurring and fix the issue. After the investigation is complete, then it is safe to delete the core files since you won’t need their information anymore.
