--------------------------------
Summary: Failing tests due to timeouts caused by SSL depleting
random entropy on Jenkins
Key: SOLR-6254
URL: https://issues.apache.org/jira/browse/SOLR-6254
Project: Solr
Issue Type: Task
Components: Tests
Reporter: Steve Rowe
Tests using SSL can block on Jenkins when random entropy is depleted, causing
timeouts that trigger test failures.
I found some info about /dev/random problems on FreeBSD here:
[https://wiki.freebsd.org/201308DevSummit/Security/DevRandom], which lead me to
/etc/rc.d/iinitrandom, which gets around the limited entropy by cat'ing a bunch
of shit to /dev/random:
{code}
( 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
{code}
I think we should try the same strategy in a crontab every X minutes, to see if
that addresses the test failures.
