ASF subversion and git services commented on SOLR-16644: -------------------------------------------------------- Commit 69ab812a7fbe2c9bd6545048c56a1b39fb46b078 in solr's branch refs/heads/branch_9x from Jan Høydahl [ https://gitbox.apache.org/repos/asf?p=solr.git;h=69ab812a7fb ] SOLR-16644: Only warn entropy on Linux (#2000) (cherry picked from commit 4e9b330d9e7adb8eb866df8e148be21651eb6255) > Entropy warning thresholds need to be revisited > ----------------------------------------------- > > Key: SOLR-16644 > URL: https://issues.apache.org/jira/browse/SOLR-16644 > Project: Solr > Issue Type: Bug > Reporter: Ishan Chattopadhyaya > Priority: Major > Labels: newdev > Fix For: 9.4 > > Time Spent: 2h 20m > Remaining Estimate: 0h > > As per the following, newer kernels (5.15+) have recalibrated the entropy > levels from 0-4096 to 0-256. Hence, everything is throwing a warning: > {code} > Warning: Available entropy is low. As a result, use of the UUIDField, SSL, or > any other features that require > RNG might not work properly. To check for the amount of available entropy, > use 'cat /proc/sys/kernel/random/entropy_avail'. > {code} > Here's where I found out about this change: > https://askubuntu.com/questions/1427470/entropy-is-stuck-at-256-after-upgrading-to-kernel-5-15-0-47 > We might need to intelligently report the low entropy (based on kernel > version). -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@solr.apache.org For additional commands, e-mail: issues-h...@solr.apache.org
