GCC 2.7.2.2, x86... >Description: Implemented to replace CERN proxy. Over time, proxy stability kept decreasing. More and more proxy requests were refused, or hung for no particular reason. Problems were not observed until maximum cache file size was reached. Factors: Lots of spare memory, lots of spare disk, lots of spare CPU. It simply worked less and less often over time. Before removing it, I was consistently able to fail every other request, some to systems right down the hall... >How-To-Repeat: I'm not sure, given this is a production environment, I don't have time to test it a lot. It worked perfectly fine when only the IT department used it, but when we rolled it out for general use, it just stopped working eventually. More than 500 users, 20-30 concurrent, 5 remote WAN sites is our environment. We had 250K proxy hits in the two weeks it was up. >Fix: >Audit-Trail: State-Changed-From-To: open-analyzed State-Changed-By: chuck State-Changed-When: Sat Apr 12 15:28:30 PDT 1997 State-Changed-Why: Can you send us the configuration files you were using for the proxy? That may help us analyze things. State-Changed-From-To: analyzed-suspended State-Changed-By: chuck State-Changed-When: Sun Apr 13 21:28:25 PDT 1997 State-Changed-Why: No feedback received. User stopped using proxy, so I can't suggest settings to try.
