USG110 : Memory limiter question

kyssling

Hello,

about one year ago we had problem with disconnecting VPN from USG110.

These settings (after long months research with Zyxel) problem solved:

Router> debug memory-limiter drop-cache-periodic 60
Router> debug memory-limiter watermark 10000
Router> debug memory-limiter activate

After this settings, VPN working without problems and everything is fine.

Unfortunately, lately it sometimes happens that the router is overloaded by activating memory-limiter
and we cannot work with internet about  3-6 min.

For example : Today, between 9:31 - 9:36, the watermark was activated 18 times. We receive Alert emails:

No. Date / Time Source Destination     Priority Category Note     Message

2020-05-13 09:31:11     alert system System remaining 63983 4KB pages, Memory limiter activate

2020-05-13 09:31:15    alert system  System remaining 63969 4KB pages, Memory limiter activate
2020-05-13 09:31:15    alert system  System remaining 64008 4KB pages, Memory limiter deactivate     2020-05-13 09:31:41    alert system  System remaining 64016 4KB pages, Memory limiter deactivate

2020-05-13 09:31:48    alert system   System remaining 63981 4KB pages, Memory limiter activate

The result is the inability to browse the websites or check emails : browsers report: "Connection has timed out."

Very thanks for help. Vaclav

Regarding to this case,
after issue occur, can you private message the diagnostic information for check further?
Also, what is firmware version of device?
