What are possible reasons that can cause Gurobi to crash in a Java application with a core-dump?
Ongoing
I have written an application that uses Gurobi at its core. As part of it functionality, it stores/reloads Gurobi models to/from MPS files. This has been working well so far.
However, I am now facing the issue that the application crashes with a Java core dump during the reload step. I.e. the initial optimization in Gurobi and storage to the MPS file works fine, but the program crashes, when trying to reload the MPS file. The relevant error output is this:
Set parameter TokenServer to value "10.1.0.93"

# A fatal error has been detected by the Java Runtime Environment:
#

# The crash happened outside the Java Virtual Machine in native code.
# See problematic frame for where to report the bug.

I copied the content of the file `hs_err_pid23413.log` here: https://pastebin.com/putFq1ne
The software (and Gurobi) are running inside a Singularity container with the following properties:
* Gurobi 10.0.2
* JRE version: OpenJDK Runtime Environment (11.0.19+7)
* Ubuntu 18.04.6 LTS
My question is:
* What could be causing a problem like this and what are possible ways to debug this?
* Is there an option to make Gurobi output more debug-information?
I am currently very much in the dark on what could be causing this issue, so any suggestion would be greatly appreciated!
Thank and kind regards,
Michael
