Wingate - System Cache

[breese]

I am beta testing Wingate (V 6.5.2) to replace my Winproxy firewall / Nat
Over the last 3 weeks I have had my W2K box freeze to the point the screen connected to it goes black and will not recover without a hard restart.

The only software running on the box is Wingate and Symantec Antivirus
I do not see any other built in Virus software within Wingate.

It has 2 network connections and they are correctly identified in Wingate
External - Connected to my DSL model with a pppoe driver (Dynamic IP) and is a 10/100 network card
Internal - Intel server 1 gig card connected to my internal network 1 gig switch

As time passes from a fresh restart, the system cache grows
The system is a 2.8 CPU (none hyperthread) with 1 gig of ram.
I have a task scheduler running Disk Cleanup and defrag every night.

The load on the system is not very big... This is my home firewall.

The OS is XP Pro with SP3
Performance options are set for
Processor scheduling - Programs (I assume correct for Wingate)
Memory usage - System Cache

My current task manager shows
Physical memory
Total 1048032
Available 660600 up and down
System Cache 577300 up and down

Kernel Memory
Total 110900
Paged 98588
Nonpaged 12400

I can not understand the System Cache continually growing to this size after a restart shows it starting out at 320200 with Wingate running.

I can collect any and all logs as requested.
Thanks


in 18 minutes the System Cache is up to 58800
Wingate has
800+ handles
26 Threads
10,292 in memory

Hi

The system cache is the memory the system uses to cache recently accessed files. If this number keeps growing, it indicates that something is touching a lot of files.

however 58MB is a relatively small value even on a 1GB machine. My desktop here for instance currently has nearly 1GB in use by the system cache.

The Symantec AV - does it have a firewall, or does it do traffic filtering?

Some AV systems really interfere with WinGate, since they install NDIS packet filtering drivers etc. Also make sure it's not scanning the WinGate folders, else it can hurt performance when WinGate writes a line to a log file etc.

p.s. re application tuning, WinGate is a service, not a foreground app, so I'd set it to favour background tasks for processor, and programs for memory.

has a good description of how to interpret the System Cache and other values you see in the performance tab of Task Manager.

I recovered a minidump file
it shows an association to qbikhkXP.sys

I have also seen this was reported back in Aug 2007
forums.qbik.com/viewtopic.php?p=29611&sid=d26196bd702655c6d3121b3d35728753

I have tried to attach the dump file as a zip but the site gives me

Could not upload attachment to ./files/41440_11159605580922b5cf6a4b159bcbf9ec.
