Do you see mem leakage with dgelsy routine only?
have you try to set MKL_DISABLE_FAST environment variable to 1 or call mkl_disable_fast_mm() function?

We used mkl 11.1.1. before and start using mkl 11.3.3 recently. The memory leak seems only with mkl11.3.3. We will try the env variable MKL_DISABLE_FAST.

I got no memory leak using MKL 2017.2.174 with MKL_DISABLE_FAST=1. I am testing if MKL_DISABLE_FAST=1 is still necessary using MKL 2017.2.174. (With MKL11.3.3 and MKL_DISABLE_FAST=1, I still get some leaks.)

MKL_DISABLE_FAST=1 is not necessary if we use MKL 2017.2.174.
