[jira] [Resolved] (TS-758) HostDB fails to insert RR entries (allocation fails) claiming DB is full

["Alan M. Carroll (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TS-758?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan M. Carroll resolved TS-758.
--------------------------------

       Resolution: Later
    Fix Version/s:     (was: 3.1.1)

The behavior is by design. It is usable as is. However, in the long term we need to improve HostDB in general due to a number of issues, this being only one. We may in fact want to redo the entire DNS / host resolution system.

> After running in forward proxy for a few days, I got a bunch of these errors:
> [May  3 17:13:11.574] Server {140488838387680} WARNING: out of room in hostdb for round-robin DNS data
> [May  3 17:13:11.726] Server {140488838387680} WARNING: out of room in hostdb for round-robin DNS data

> [May  3 17:13:17.114] Server {140488838387680} WARNING: out of room in hostdb for round-robin DNS data
> I'm not sure why it thinks it's out of room, there is no way I've filled my hostdb cache (I'm fairly certain). I'm not able to reproduce the problem (easily).
