Hi @natel9178 !
Thanks for thorough description of the problem. If I understand correctly, you are running 32 parallel models here. Additionally I see these in the stacktrace:
13# dali::ThreadPool::ThreadMain(int, int, bool) in /opt/tritonserver/backends/dali/dali/libdali.so
15# 0x00007F6BFFDBE609 in /usr/lib/x86_64-linux-gnu/libpthread.so.0
This would suggest a problem with CPU threads used. Could you try to reduce num_threads=1 in DALI pipeline definition and see, if this helps? Generally, CPU operations in DALI use thread-per-sample mapping. So if you have batch_size=1 there won't be any difference, still only one thread will be used.
If this does not help, could you support us with a core dump or a repro, that we can run on our side?
