Opened: Jul 08, 2015 Severity: 3-Major
When there are many entries in the session database and a user attempts to delete them with "lsndb del all", this can cause lsndb to core with "Assertion 'size < bin_key_size' failed". The user may see lots of "Error: Connection to internal DB failed (err: Cannot assign requested address [99])" messages displayed to the console. In addition not all of the session database entries will be deleted.
- Session database cannot be properly cleared using the lsndb util.
- LSN is configured with persistence, inbound-connections automatic, or PBA enabled. - There are over 100,000+ Session database entries (e.g. persistence, inbound, or PBA entries). - User attempts to manually delete all entries with "lsndb del all"
None
lsndb no longer cores while deleting large amounts of session database entries.
