We are using Mcafee webgateway 6.x. Now a days we are observing that the users are getting a blank page when trying to access internet.
When looking into the logs we found memory overload messages. looking at this we have enabled the mutiprocessing mode. However still the problem arrives intermittently.
We had created a tcpdump when the issue was reproduced. In the below screenshot we are able to see that when the three way handshake successfully happens between the client - 18.104.22.168 and the proxy - 22.214.171.124, there is 503 service unavailable error return code from the proxy. Then there is a request from the client to proxy for cisco.com, which fails to load and the user gets and blank page.
I have attached the pcap file if anyone wish to look further in the capture.
An immediate reply would be appreciated.
A 503 is indcative of overload related issues, please be sure to file a SR so we can get it looked at. If you have an SR please let us know it.
Please find the SR # <4-3456312396 no which we have already opened with support and have shared the same dumps as attached here. We have no response from team yet.
Sounds good, looks like we're waiting on a feedback file, please deliver that to the case and follow the advice already given by Ralf to remediate the issue.
