<span id="BugEvents">Our developers have investigated case 162101 and came to conclusion that it's not a bug in ActiveAnalysis. ActiveAnalysis places the request data in
HTTP headers and they have a limited size of 16
KB. Hence, when the requested data exceeds this limited size the data gets truncated and hence it causes the problem.
You will need to change the </span><span id="BugEvents">Http.sys registry settings for IIS </span>in order to resolve this.The steps to do the same are explained below.
1. Locate registry key path "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters".
2. Add registry key "MaxRequestBytes" (DWORD 32-bit values) with decimal value "16777216" under this path.
3. Add registry key "MaxFieldLength" (DWORD 32-bit values) with decimal value "65534" under this path.
4. Restart your machine.
