Dear Kolinko,
Thanks for the link below.
I have seen this resolution before.
But the tomcat version is not applicable. I was wondering what else might cause
this issue.
The exact issue is that only 8192 bytes of POST request are read, when using
below code.
> BufferedReader in = request.getReader();
> while ((keyValuePair = in.readLine()) != null) {
> arrKeyValue = keyValuePair.split("=");
Same code reads whole data within one environment and reads only 8192 bytes in
other environment.
All the software versions in both environments are same.
Only diff is that they physically 2 different hardware servers. I am sure some
setting must be different. Would like to know, which is that setting to cause
this issue.
Thanks and Regards,
Harish

The code looks OK.
The readLine() implementation is provided by
org.apache.catalina.connector.CoyoteReader.
Looking at the history of that class, there is a known issue
https://issues.apache.org/bugzilla/show_bug.cgi?id=42727
"CoyoteReader readLine returns null for some post request bodies that
are a multiple of MAX_LINE_LENGTH in size"
but it should have been fixed in 5.5.27 and thus in 5.5.28 if that is
the version that your customer is using.
