Segmentation fault(core dump) & huge data/core generated

[klaus99815]

Use Apollo 5 0 and lgsvl are jointly simulated. After LG end repeatedly connects Apollo, the Apollo end will produce segmentation error. Due to the huge data / core generated, there is insufficient memory and Apollo segmentation error. The generated data / core file will reach more than 40 g, because the memory of home is about more than 40 G. What is the reason? Is there a way not to generate core files. In the end, it is because the huge core file is generated that leads to the segmentation error, the bridge end is broken, or the bridge is broken that leads to the segmentation error..

Below command sets the core dump file size to unlimited to ensure that the core dump file is complete. The core dump contains the full image of the application's address space, including code, stack and heap (malloc'd objects etc.) so the size will be large. https://github.com/ApolloAuto/apollo/blob/266afbf68d83fa6fac7a812ff8a950223f5ab2c0/scripts/bootstrap.sh#L24-L26
