strange cookies appearing in my WOLogs

Hi all,

Does anybody has experienced that your logFile from a woapp logs 
cookies (or messages) from another server?. I know that this sound 
weird but the logs are real and further more, those messages/cookies 
don't belong to any of my woapps, worst yet, in some logs where there's 
the server name, this don't match with the name of my woserver, not at 
all, not even close to the name.

Here's a line of my logFile from one of my woapp:
[2005-02-14 11:30:16 CST] <WorkerThread15> CookieParser: Found a null 
cookie value in: 'PIDMI=080438658933000; pidmid=111816650793250; 
pidmid1=111816650793250; pidmid2=L01023051; pidmid3=A; 
PIDM_portal_sistema=L01023051; BRN231=11030; LLAMA97=1983; 
iduser=111877440236562; nivel='. Will continue by setting value to the 
empty string.

I know that PIDMI ,pidmid, PIDM_portal_sistema, etc, are variables with 
their corresponding values, and I can recognise some of them because 
they are student data (I work in the highschool branch of a university) 
but there are a lot of servers in the university branch that makes the 
task hard to find from which application are this messages about.

I suspected that could be something with the network switches or 
something with the network configuration so at onetime I chatted with 
some network guy at the university and he just say "Hm, man, that's 
weird" and that was it!.

Does anybody knows or had heard of something like this?
