Summary: java.io.IOException when reading data
Product: Tomcat 5 Reporter: Mario Camou <mcamou>
Component: Servlet & JSP APIAssignee: Tomcat Developers Mailing List <dev>
Severity: normal

Version: 5.5.12

Description Mario Camou 2006-03-03 02:39:11 UTC
I have an application that sends data to a servlet. It sends a data file, usually 100 lines where each line 
is 116 characters long.

I am getting the following exception. It does not occur all the time, but it seems to occur when the 
server is especially loaded:

        at org.apache.catalina.connector.InputBuffer.reset(InputBuffer.java:439)
        at org.apache.catalina.connector.CoyoteReader.reset(CoyoteReader.java:133)
        at org.apache.catalina.connector.CoyoteReader.readLine(CoyoteReader.java:190)
        at mx.com.cie.tarificador.parser.Receiver.receive(Receiver.java:87)

(mx.com.cie.tarificador.parser.Receiver.receive is a method I call from the doGet and doPost servlet 
methods to do the receiving and parsing of the file).

Note that this is not a dupe of bug #34829 since in this case the error occurs even though the line is 
116 characters long.

I cannot test on 5.5.15 because of bug #38835. I also cannot test on 5.5.14 because this is happening on 
a productions system and bug #34829 affects it.

This might be a duplicate of
http://issues.apache.org/bugzilla/show_bug.cgi?id=38346 which has already been
fixed in HEAD. The patch will be included in 5.5.16 which will be released in
the next days. Please give feedback, if 5.5.16 fixes your problem.

You also refer to 34829. That might have been fixed by the same patch.
Concerning 38835 please see the comment bei William Barker there.

Tested on 5.5.15 and the problem is still there. It is intermittent, it doesn't happen all the time and it 
might happen on one request and not happen on another one just like it. I will test on 5.5.16 as soon as 
it's out.

No further comments from OP. Assuming it was a duplicate and is now fixed.
