In my linux embedded device, I run prngd in the following way:

prngd /var/run/egd-pool

In the system log I am getting the followiong errors:

Is there a way to understand why prngd gives me such errors? Thanks.

After investigating, those errors are generated because in the prngd configuration file (/etc/prngd.conf) those file are used to generate entropy. It is clearthat if those files are not present on the device, prngd generate an issue. To solve this, is sufficient to comment the lines related to the missing files.
