I am unsure what you're asking here. The primary function of the machine in question is to function as a router - it performs authentication, email proxying, VPN, DHCP leasing, DNS and many other things on top of web access via Squid, so controlling the memory usage to this degree is not really feasible. However, I can provide the output of top for the system, if that would be helpful. Typically, other processes use very very little memory, and none of them route through Squid itself. > > I have a tiny proxy with 1GB ram and it works with no problems that I know > of yet with 3.4.X. > > Since it's a 32bit machine and has couple things I have a spec file that > worked fine for it on the latest build of squid. > > If you do not use authentication remove any of the non-relevant build > instructions.. In the primary instance, we run NTLM authentication via direct proxy, so I'll do a build using that without all of the other authentication methods. > > Also if you can get into a position where all of your machine details are > known such as "what each process uses??" you can answer yourself more. > > ps avx -L |grep squid > can give more but if you do have top output for all squid process and > subprocess it will be nice. > as you can see these processes do use an amount of ram but if make sure that > the ram is "slipping" from one way or another and in not accounted in top we > have a more solid ground on that. > > What would "http://squid_ip:port/squid-internal-mgr/mem"; > Would give us?

It's an office of ~30 people, the majority of which access the Internet via transparent proxying, one or two using direct proxy for various reasons. > > I would try to run the proxy with no cache at all for about 24\48 hours to > see if there is a peek in the FD usage or any load on the service which can > describe what you are talking about. As mentioned earlier, I have already done this, and the load+FD usage is essentially at a constant rate of what is described in the manager info page linked to earlier. > > There is always the possibility for a memory leak and it's not always > related directly to squid.. > > What are the network requirements? Are you using WCCP(for example)? Can you be a little more specific in what you're asking here? We're not using WCCP. Thanks, Nathan.
