# Causes Of Tikv Server Oom

+ Improper block-cache configuration causes OOM
+ The Coprocessor received a large number of large queries, the amount of data return was too large, and the sending speed of gRPC could not keep up with the speed of the Coprocessor outputting data, resulting in OOM
+ Other processes take up too much memory
