Hi, Was the number of open files changed on ubuntu1 recently?
The OpenJPA builds recently started failing with an error like this one : <snip> Caused by: java.io.FileNotFoundException: /home/hudson/hudson-slave/workspace/OpenJPA-20x-deploy/2.0.x/openjpa-persistence-jdbc/target/test-classes/org/apache/openjpa/persistence/embed/EntityA_Embed_MappedToOne.class (Too many open files) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:106) at org.apache.openjpa.lib.util.J2DoPrivHelper$29.run(J2DoPrivHelper.java:688) <snip> In the past we've solved this by increasing the number of open files (4096 in my case). FWIW the builds are working on ubuntu2. Thanks, -mike
