[jboss-jira] [JBoss JIRA] (WFCORE-1403) UDP Syslog handler cannot log first message after reconnect

[James Perkins (JIRA)]

     [ https://issues.jboss.org/browse/WFCORE-1403?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

James Perkins closed WFCORE-1403.
---------------------------------
    Resolution: Rejected


This is working as expected. It's the way that {{java.net.DatagramSocket.send()}} is implemented. The first invocation on a down server doesn't raise and error. The second invocation raises the error and the third invocation works as expected.

> In case when logging to syslog through UDP protocol is configured and syslog port becomes unreachable then after syslog restart first message can be thrown away. It happens when odd number of messages is attempted to be logged during syslog is unreachable. It is caused when port unreachable is returned during logging attempt, then another log attempt automatically fail even if syslog server has been started meanwhile.
