Mano Kovacs commented on SOLR-10352:
------------------------------------
[~ichattopadhyaya], [~esther.quansah], may I ask why the final commit makes
comparison with 30000? AFAIK, it never goes over 4096 [1].
[1] "The read-only file entropy_avail gives the available entropy. Normally,
this will be 4096 (bits), a full entropy pool." -

> We should add a warning in the startup script for Linux, if the output of the
> following is below a certain threshold (maybe 300?). The warning could
> indicate that features like UUIDField, SSL etc. might not work properly (or
> be slow). As a hint, we could then suggest the user to configure a non
> blocking SecureRandom (SOLR-10338) or install rng-tools, haveged etc.
