Error reading task outputhttp

I think my hdfs may be sick but when I run jobs on out 8 node cluster I have
started seeing

11/10/26 15:42:30 WARN mapred.JobClient: Error reading task outputhttp://
glados6.systemsbiology.net:50060/tasklog?plaintext=true&taskid=attempt_201110261134_0009_m_000001_2&filter=stdout
11/10/26 15:42:30 WARN mapred.JobClient: Error reading task outputhttp://
glados6.systemsbiology.net:50060/tasklog?plaintext=true&taskid=attempt_201110261134_0009_m_000001_2&filter=stderr
11/10/26 15:42:36 INFO mapred.JobClient: Task Id :
attempt_201110261134_0009_r_000080_2, Status : FAILED
java.lang.Throwable: Child Error

and then the task fails - after a few of these the job fails
These are jobs which have worked in the past

Any ideas??
