LTM ICAP Upload Issue

Hi,

 

I've setup the F5 to do AV Scanning via LTM and Internal VS with ICAP to a AV Scanner. Everything works ok up to about 2 or 3MB file size, after that the upload doesn't get passed through to the web server.

 

I've done a tcpdump on the ICAP interface and when doing the 4M file upload I see the F5 passing the file up to the Scanner but do not see the final multipart boundary as if it is truncated. The scanner responds with an OK and passes back to the F5 what it has been sent but nothing gets forwarded to the web server. For the 2M file I can see the final boundary in the ICAP trace between the F5 and AV Scanner and the response gets passed back to F5 and forwarded to the web server OK.

 

I've taken the request adapt profile off the main VS and uploaded 20M files without any problems,

 

any ideas appreciated..
