Slow performance, ProxySG outages occurring, or ICAP queuing after upgrading ASG to SGOS 18.104.22.168/22.214.171.124 and performing "restore defaults"
Last Updated June 25, 2018
This alert only applies to Advanced Secure Gateway (ASG) products running 126.96.36.199 through 188.8.131.52 inclusive.
After upgrading to 184.108.40.206 or 220.127.116.11 and performing “restore defaults” can cause the number of available ICAP scanning connections to go from 250 down to 25. Thus reducing the performance of the ASG dramatically.
This issue could be present on factory manufactured systems installed with 18.104.22.168 through 22.214.171.124.
To see if the issue is present, you can check via Management Console, the max connection settings can be checked using the advanced url /OPP/statistics, for example:
https://<ProxySG IP address>:8082/OPP/statistics
or via CLI, from enable mode:
Blue Coat ASGSeries#show advanced-url /OPP/statistics
There is a workaround for this issue (see below) and there will be a fix in an upcoming release of 6.7. This Alert will be updated once the release becomes available.
The workaround for this issue is to manually set the local connections to 250.
From the CLI, get into configure mode then content-analysis then execute the following for both request and response modification:
Blue Coat ASG Series#(config content-analysis)edit bluecoat-local-request Blue Coat ASG Series#(config icap bluecoat-local-request)max-conn 250
Blue Coat ASG Series#(config content-analysis)edit bluecoat-local-response Blue Coat ASG Series#(config icap bluecoat-local-request)max-conn 250
