When using ABAQUS 6.14 (but also ABAQUS 2018) on ubuntu 18.04 everything seems to work fine except the termination of the standard process (the process started when performing an implicit analysis -- if you are not familiar with this it doesn't matter).

The analysis indeed works as one can also see in a log file (the .sta file, for those who are familiar with abaqus) the message THE ANALYSIS HAS COMPLETED SUCCESSFULLY. The output database contains the analysis results. However, after the analysis has been completed, the process standard remains in a sleeping status using 0% CPU and keeping the same amount of RAM as when it was running.

From strace I get:

Like if the two processes were in a deadlock state. Moreover, the commands

pid -p 7002

and

pid -p 7010

do give an empty output. The dirs /proc/7002 and /proc/7010 do not exist.

The only abaqus-related processes executing are

On ubuntu 16.04 the exact same version works like a charm. Here the same strace on ubuntu 16.04 (with the same kernel version as my 18.04, i.e. 4.15.0-29):

Has someone a good idea how to solve this? Or in which direction should I investigate further.
