What problem was encountered?

There seems to be some kind of deadlock. Every command takes ~8 seconds. Also the stack trace.

See the attached strace.log.

How can we reproduce the problem in the simplest way?

Unsure.

Have you found a mitigation/solution?

Unfortunately, no.

The issue seems to be in the version check. Running the following is near-instant:

$ time azcopy --skip-version-check --version
azcopy version 10.22.0

real	0m0.017s
user	0m0.010s
sys	0m0.007s

Hi there! Thank you for bringing up this issue. I was able to repro this, and we are working on a fix. In the meantime, please use --skip-version-check to minimize the 8 second lag.
