#4 Application logging hangs when Nagios unavailable

[hnh]

Hi,

In the event of the Nagios server being down the application hangs while trying to log an event using the log4j Nagios appender. Is this an expected behavior or my configuration is missing something. Here is the log4j.properties:

log4j.rootLogger=DEBUG,NAGIOS

log4j.appender.NAGIOS=org.apache.log4j.nagios.NagiosAppender
log4j.appender.NAGIOS.Host=dc2vplnag01.rbauction.net

log4j.appender.NAGIOS.ConfigFile=send_nsca.cfg

log4j.appender.NAGIOS.ServiceNameDefault=nscasvcname

log4j.appender.NAGIOS.UseMDCHostName=true
log4j.appender.NAGIOS.MDCHostNameKey=nagios_host_name
log4j.appender.NAGIOS.InitializeMDCHostNameValue=virtualhost

log4j.appender.NAGIOS.useShortHostName=true
log4j.appender.NAGIOS.MDCCanonicalHostNameKey=nagios_canonical_hostname
