Tested with the global counter, the log message increments correctly.

Feb 24 15:16:58 local/tmm info tmm[2253]: iRule: Received Server Data 45

Feb 24 15:16:58 local/tmm info tmm[2253]: iRule: Received Server Data 46

Feb 24 15:16:58 local/tmm info tmm[2253]: iRule: Received Server Data 47

Feb 24 15:16:59 local/tmm info tmm[2253]: iRule: Received Server Data 48

Feb 24 15:17:00 local/tmm info tmm[2253]: iRule: Received Server Data 49

I then wrote the XML received in the packet to the log from SERVER_DATA. 

 
     set payload [TCP::payload]  
     set xml [string range $payload [string first      log -noname local0. "iRule: $xml"

Although my client get the XML returned, the XML is not logged. So it looks like the SERVER_DATA event is not fired.
