Description

when running load test using mina/Http protocol
i got Decoder exceptions during "medium/high load" when using 5 thread.

2007-12-07 12:43:35,997|pool-3-thread-8|ERROR|HTTPTestCase.exceptionCaught(49)|error: org.apache.mina.filter.codec.http.HttpRequestDecoderException: Unsupported HTTP version: 9-95-ea36a8c0" (Hexdump: 0A 41 63 63 65 70 74 2D 52 61

the "9-95-ea36A8c0" belongs to the ETag header which is the 5 header in the response.

i checked the traffic using wireshark and noticed that:

• HTTP request/response seem to be ok (all 200 OK)
• 3 to 5 HTTP request where send before first response
• multible responses would follow each other.
