How many clients are you protecting behind your S1104?
You may be misinterpreting the memory usage, so you can look at this article:
Explanation of Memory Usage Shown in the Output of top KB64409 kc.mcafee.com
Can you send the following output:
Thank you Matt for your early response!!
I am protecting 3 VLANs behind the firewall. The VLAN for the internal users (around 50 clients), the VLAN of the video and physical access control to the building, and the VLAN for wifi connections to the visitors.
We are running on V8.3.
Follows the output of the command requested.
and some minutes later ...
Thanks in advance.
We are thinking that your firewall might be spawning too many processes based on the "Approaching the limit on PV entries" error.
Can you send us the output of 'pss'?
There might be a problem with your sendmail configuration that is causing a loop. Have you modified sendmail at all recently? If sendmail has spawned way too many processes, you can limit sendmail to 50 processes by following the KB:
Thank you Matt.
I performed the changes to limit sendmail to 50 processes as mentioned.
Tomorrow morning I´ll send you the output of pss command.
I have an additional doubt. We don´t have an internal mail server. I mean, we are using a POP3 mail server hosted on the cloud. Even that, is necessary to configure the sendmail or smtp proxy on the appliance?
Thanks in advance
There are definetly too many sendmail processes spawned, but not enough I think to cause this problem.
I am in training today and it is going to be hard to respond. I suggest opening a ticket with support and they can do a remote session and figure out what is happening and prevent it from occuring.
OK, I´ll do.
