ChatGPT analysis:

The provided system traceback indicates that the Linux Out of Memory (OOM) killer has been triggered to terminate a process due to a severe memory shortage. In this case, the process with PID 34174, which is named "ansys.e," was killed.

Here's a breakdown of the information in the traceback:

Breakdown

1. `[13805.080178] oom-kill:constraint=CONSTRAINT_NONE,nodemask=(null),cpuset=7a592394a755940f4abe040863983ad11c135aa1ddb8ddab2d0b20af5f71cd00,mems_allowed=0,global_oom,task_memcg=/docker/7a592394a755940f4abe040863983ad11c135aa1ddb8ddab2d0b20af5f71cd00,task=ansys.e,pid=34174,uid=0` - `oom-kill`: Indicates that the OOM killer is activated. - `constraint=CONSTRAINT_NONE`: The constraint on memory usage is set to none, meaning there are no specific restrictions. - `nodemask=(null)`: No specific memory nodes are specified for allocation. - `cpuset=7a592394a755940f4abe040863983ad11c135aa1ddb8ddab2d0b20af5f71cd00`: Specifies the CPU set of the process. - `mems_allowed=0`: Indicates that the process is not allowed to use memory from any specific NUMA node (0 in this case). - `global_oom`: Suggests that this is a global OOM event affecting the entire system. - `task_memcg=/docker/7a592394a755940f4abe040863983ad11c135aa1ddb8ddab2d0b20af5f71cd00`: Specifies the memory control group (cgroup) associated with the Docker container running the process. - `task=ansys.e`: Name of the process that was killed (ansys.e). - `pid=34174`: Process ID of the terminated process. - `uid=0`: The user ID of the process owner (0 typically represents the root user). 2. `[13805.080613] Out of memory: Killed process 34174 (ansys.e) total-vm:19713496kB, anon-rss:7374568kB, file-rss:516kB, shmem-rss:8960kB, UID:0 pgtables:21208kB oom_score_adj:0` - `Out of memory`: Indicates that the system ran out of available memory. - `Killed process 34174 (ansys.e)`: Specifies that process 34174, named "ansys.e," was killed to free up memory. - `total-vm:19713496kB`: The total virtual memory size used by the process (in kilobytes). - `anon-rss:7374568kB`: The anonymous (non-file-backed) resident set size, indicating how much physical memory the process was using (in kilobytes). - `file-rss:516kB`: The resident set size for file-backed memory (in kilobytes). - `shmem-rss:8960kB`: The resident set size for shared memory (in kilobytes). - `UID:0`: The user ID of the process owner (0, the root user). - `pgtables:21208kB`: The size of page tables used by the process (in kilobytes). - `oom_score_adj:0`: The OOM score adjustment value for the process (a score that helps the kernel prioritize which process to kill when low on memory). In summary, this traceback shows that the "ansys.e" process was killed due to a severe memory shortage on the system. The process was using a significant amount of memory, and the OOM killer was triggered to free up memory resources for the system to continue running.

Discussion

The traceback shows that it is an SIGTERMsignal (Signal 9) triggered by an Out Of Memory (OOM) error. This is interesting because it means it could be avoided by increasing memory allocated to the container. But also it shows that the instabilities found in gRPC in non-dockerized environments are going to require a different setup (MAPDL local).

Thank you @germa89 , in code.zip is the code that produces this issue. Some modification may be needed to get it to work (I am running MAPDL locally, on windows). FieldComputer.py is the helper class that is called by compute_for_multiple_mesh_size_wb.py This code does steady state electrical analysis using MAPDL. Original mesh (accessible using sharepoint link) is mesh200 elements that are then converted to solid232 (I've experienced some connection termination when running emodif method). BCs are added and the electrical field is computed. The electrical voltage is saved to vtk through the mapdl.result.save_to_vtk, which fails often. sharepoint link to cdb files code.zip
