~PoshRuntimeImpl(): does not exit #2493
Description
Required information
Operating system:
Ubuntu 22.04 LTS
Compiler version:
GCC 11.4.0
Eclipse iceoryx version:
2.95.6
Observed result or behaviour:
The runtime does not exit from iox::runtime::PoshRuntimeImpl::~PoshRuntimeImpl()
Expected result or behaviour:
Correct exit of the runtime
Conditions where it occurred / Performed steps:
We have many pipelines for our code, and occasionally one of the tests gets stuck on this destructor. To reproduce the issue, I ran a single test on my machine for a week, and it finally happened today.
Additional helpful information
We have GDB open, and this is the stack trace. Could you please help us debug it and find out why this happens?
