I run abaqus cae simulation on a Linux server which has 32 cores. But because of some reason the server is not able to run with more than 6 cores (Using parellelising option in Abaqus cae job). If I use 7 or more cores in parellelising option in the Abaqus job window the process is going into sleep state. The picture above is the output of the htop command. If I restart my server then all 32 cores are working fine.Anyone knows the solution for this problem without the need to restart the server? 
Just given 'abaqus cae' process going into sleep in server with 32 cores
