Mark Miller commented on SOLR-6254:
-----------------------------------
bq. I think we should try the same strategy in a crontab every X minutes, to
see if that addresses the test failures.
I think it's fine as a short term workaround, but not a great solution. We
probably should just disable SSL unless we can address it in a portable way.
> Failing tests due to timeouts caused by SSL depleting random entropy on

> I found some info about /dev/random problems on FreeBSD here:

> to /etc/rc.d/iinitrandom, which gets around the limited entropy by cat'ing a
> bunch of shit to /dev/random:

> ( ps -fauxww; sysctl -a; date; df -ib; dmesg; ps -fauxww ) \
> | dd of=/dev/random bs=8k 2>/dev/null
> cat /bin/ls | dd of=/dev/random bs=8k 2>/dev/null
