hello rbayr,
may I know which JetPack release you’re working with?
I’ve attach r32.6.1 pre-build library, Topic219059_Jul11_libnvargus.so (1.1 MB) which adding some debug logs for checking the condition wait within acquireBuffer(...).
please back-up/replace the binary file and gather the logs for reference,
you’ll need also below steps to view Argus daemon logs.
$ sudo su
# pkill nvargus-daemon
# nvargus-daemon 2>&1 | tee argus-output.log
