problem with dude

i have routerboard 1100 with dude server
i route range for example: 192.168.13.0/24 to this routerboard

some ip in range have ping and up in dude router but some other aren’t
when i reboot device all probe are ok and up and after a while some of them will be disconnected
this is interesting for me when ping is down , in service when use discover for find active services it find ssh for this ip is up
What could be the problem…!!!
Configuration is the same across all client routers

it’s amazing. i solved the problem with increase interval time up to 60 second… !!!

Check CPU usage of unit running Dude. You didn’t say how many devices you were monitoring. I found hEX getting way behind spending almost all its time in encryption package when monitoring ~250 devices with (default) “secure mode” on. Removed secure mode and Dude came back to life.

thats right, thank you
