Ant: "IOException: Error writing request body to server" while deploying to tomcat

I'm new to StackExchange, so please refrain from my possible mistakes ...

I have searched for answers but none of them apply to my situation as this build and deployment actually works, but the result is an IOException at the end of the deployment call though.

I am creating a deployment script in ant. Part of the deployment uses this taskdef:

<taskdef name="tomcatdeploy" classname="org.apache.catalina.ant.DeployTask" />
<target name="-tomcatdeploy" description="deploy to tomcat">
    <echo>deploying from client</echo>
    <tomcatdeploy
            url="http://32.0.26.146:8080/manager/text"
            username="<veryHardToGuessUsername>"
            password="<veryHardToGuessPassword>"
            path="/avlsweb"
            war="/mnt/s/Web/Avlsweb/BambooBuilds/TEST/${nt-server.dir.test}_Tc${version}/avlsweb##${version}.war"
            version="${version}"
            />   

      

        
        
        
      

    

We are using Bamboo as our build server. This worked great for a number of assemblies. However, I recently got this build error:

/mnt/data/bamboo_home/xml-data/build-dir/AVTST-TEST15-JOB1/AvlswebScripts/Ant/build.xml:286: java.io.IOException: Error writing request body to server

The weird thing is that the build works and it works fine for tomcat as well. However, for some reason, an IOException is thrown after deployment, resulting in a "red" crash message in Bamboo. A few additional notes:

• Tomcat manager - script user configured
• The bamboo build server with ant runs on the same server as the tomcat app server, but bamboo and tomcat for targeting run as separate servers on different ports.
• Build Server: Atlassian Bamboo 5.9.0
• Ant version: 1.9.2
• Tomcat version: 8.0.15
• Java version: 1.7.0_67

Any ideas?
