tomcat fails to connect to a logging server while starting ubuntu

Question

i installed Tomcat6.0 to start at startup, using a init.d script. while loading a web service, who tries to connect to a logging server, i get an exception:

log4j:ERROR Socket exception java.net.SocketException: Network is unreachable at sun.nio.ch.Net.connect0(Native Method) at sun.nio.ch.Net.connect(Unknown Source) at sun.nio.ch.DatagramChannelImpl.connect(Unknown Source) at org.graylog2.GelfSender.initiateChannel(GelfSender.java:29) at org.graylog2.GelfSender.(GelfSender.java:23) at org.graylog2.log.GelfAppender.activateOptions(GelfAppender.java:125) at org.apache.log4j.config.PropertySetter.activate(PropertySetter.java:307) at org.apache.log4j.xml.DOMConfigurator.parseAppender(DOMConfigurator.java:295) at org.apache.log4j.xml.DOMConfigurator.findAppenderByName(DOMConfigurator.java:176) at org.apache.log4j.xml.DOMConfigurator.findAppenderByReference(DOMConfigurator.java:191) at org.apache.log4j.xml.DOMConfigurator.parseChildrenOfLoggerElement(DOMConfigurator.java:523) at org.apache.log4j.xml.DOMConfigurator.parseCategory(DOMConfigurator.java:436) at org.apache.log4j.xml.DOMConfigurator.parse(DOMConfigurator.java:999) at org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:867) at org.apache.log4j.xml.DOMConfigurator.doConfigure(DOMConfigurator.java:755) at org.apache.log4j.xml.DOMConfigurator.configure(DOMConfigurator.java:891)

but the funny thing is that the same web service, while loading, few second later, tries to connect to a local database and succeeds. there are 2 network interfaces, a local one, and another one for the internet. i'm working on a virtual machine, with Ubuntu 12.04 on it. the 2 network adapters are of type VMXNET3 any ideas? thanks

Answer 1

Found the reason: it takes longer for the network adapter to load than the tomcat. it was on a VM.
