clebert suconic commented on ARTEMIS-618:
-----------------------------------------
The only 512 in use is at the initialization of libaio, where we instantiate a
file to be used to shutdown the context. (LibaioContext).
Please provide some new stack traces to see if that matches the issue you have.
Otherwise we always inspect the alignment of the device before creating a file
and a buffer. Even so, libaio should fallback to 512, as it's a requirement
from POSIX. This shoudn't cause an issue.
so, please provide some more information. It could be the device you're using.
