We are using 2 ASG appliances with content filtering. They are placed in DC and DR (operate independently). Yesterday we observed that all the PDF files and xcel files getting blocked (in both DC and DR proxy). Error appears on the web is “an error occurred while performing an icap operation server error: unknown”
In trace we observed that “EXCEPTION(icap_error): Request could not be handled”
But later in the day issue was not there. But we haven’t done any configration or policy change? What is the possible reason for this? And how to rectify this?
Thanks in advance!
