WAN disconnection

Hi,

We have changed our main router with pfsense 2.1 RC1 built on Wed Aug 21 01:57:08 EDT 2013 running on Vmware esxi 5.1.
We have multiwan scenario, with 2x lan subnets (service and production).

But we have problem, that pfsense is working worse and worse over time.

I noticed, that (when pinging 8.8.8.8 ) we have lost packets in pattern:

Last night we had lost packets (one or more) in time:
16:38
17:38
17:58
21:57
23:37
1:17
1:37
2:17
2:37
3:17
3:38
6:57

So looks like on 20 minutes (but not every 20 minutes apart) we have lost packets on WAN.
And after some time that pfsense is running (1 week) this droputs takes more time (so at first only 1 or 2 packets are lost, later 20 packets are lost and internet connection falls down for 30 seconds or more).

I do not see anything in logfiles, so can you help me solve this mysterious problem.

thank you and br,
Andrej

With further investigation i found out, that my WAN IP can be pinged normally, but user in lan cannot acces WAN.
I will try to disable multiwan, to see if problem lies there.
