Subject RE: IOException: Invalid chunk header
Date Wed, 22 Dec 2010 15:40:51 GMT
Tomcat version is: 6.0.20
Platform: CentOS 5.5
Java: Java(TM) SE Runtime Environment (build 1.6.0_11-b03)

It happens in the middle. But its not always the same point where it happens.

Hi.

1) Please provide Tomcat version, Java version, platform OS.
2) The exception message seems pretty clear : Tomcat does not like the looks of one of the

"chunk headers" of what it receives.
A protocol analyser may be the only way to see what is really being sent/received here, 
although with 50 GB of data, it might be fun..
3) since it is your application receiving this data, any idea of when it happens ? at the

beginning of the 50 GB, in the middle, at the end ?

file is received and processed by my servlet running in Tomcat. I am seeing following error
in tomcat. What could be the possible reasons for this error? I have tried googling for this
error, but no luck so far.
