Better late than never I guess :-)
Nikesh,
I work at Volvo - I'm 3rd level support with the Web Security Service Chris is talking about - I'd rather not talk about specifics of our infrastructure here, but I'm fairly certain we can help you with the problem - please either contact me or VINST ticket this to the WSS team - if you're still experiencing these issues with OTM and I'll help you out.
