Out of memory;

[ppawlo]

Hi All, I have a problem with my Firewall.
After reboot FW used about 300Mb. Then everything work good.

But always after few weeks the Firewall use 2’000MB. Then the politics installed very long.
This morning the Firewall stopped work. I could not connect to it. Clear traffic has been gone by FW, but VPN did not works.

In my logs I sow something like that;

------------------|

FW has 2GB Phisical Memory and 6GB Swap. So I do not know why the problems occurred.
FW is NGX R6.0 with HFA 04.
SmartCenter is installed on other machine.

Do you know why the problems occurred? When it was FW used about 2,000 MB of memory. Now after hardware restart everything is correct. FW again use 300MB memory.

P.S. Sorry for my English ;-).
