The subversion checkout fails at various points. I have experienced this problem
both using SCM polling with a period of every 3 minutes and with polling off and
svn pot-sommit trigger being used.

Googling brought up at least one other person who appeared to experience this
problem.

Configuration:

• Ubuntu Linux Server 9.04
• Hudson 1.316
• Hudson is run under Tomcat 6.0.18
• Subversion server 1.5.4
