进程在 ubuntu 18.04 终止前挂起

Question

当在 ubuntu 18.04 上使用 ABAQUS 6.14（还有 ABAQUS 2018）时，除了standard进程终止（进程在执行隐式分析时启动——如果你不熟悉这没关系），一切似乎都正常。

分析确实有效，因为您还可以在日志文件（该.sta文件，对于熟悉 abaqus 的人）中看到消息THE ANALYSIS HAS COMPLETED SUCCESSFULLY. 输出数据库包含分析结果。但是，在分析完成后，该进程standard仍处于睡眠状态，使用 0% 的 CPU 并保持与运行时相同的 RAM 量。

从strace我得到：

就像两个进程处于死锁状态一样。此外，命令

pid -p 7002

和

pid -p 7010

做一个空的输出。目录/proc/7002和/proc/7010不存在。

唯一执行的 abaqus 相关进程是

有人知道如何解决这个问题吗？或者我应该朝哪个方向进一步调查。

达索系统本月发布了一个错误修复：

您需要从https://software.3ds.com/Abaqus 2018更新到更多详细信息，请参见https://github.com/willfurnass/abaqus-2017-centos-7-singularity/issues/5#issue-713025844Abaqus 2018-HF16

我尝试更新Abaqus 2020到Abaqus 2020-HF5Ubuntu 20.04 和 Fedora 32，结果发现它适用于 Ubuntu 20.04 和 Fedora 32。
