Hybrid MPI+ OpenMP tasks

$

Running an application that uses MPI, OpenMP tasks in MPI_THREAD_MULTIPLE mode I get this error;

[26] trying to free memory block that is currently involved to uncompleted data transfer  operation

free mem  - addr=0x7fffc40812d0 len=175104
 RTC entry - addr=0x7fffc4081300 len=175056 cnt=1
Assertion failed in file ../../i_rtc_cache.c at line 1408: 0

This has been compiled with Intel 17 and uses Intel MPI 17. 

Any idea of how I could debug this issue?

Regards,

Luis
