ovpn-clinet v5 connection problem cpu 100% load

Hi,

I have a problem with the RB433 ovpn client.
software: >= v5 no connects

ovpn, info ovpn-out1: initializing …
ovpn, info ovpn-out1: dialing …
ovpn, info ovpn-out1: initializing …
ovpn, info ovpn-out1: dialing …
ovpn, info ovpn-out1: initializing …
ovpn, info ovpn-out1: dialing …

cpu load 100%

The problem occurs on the RB433. I threw the same configurations for RB750 and there is OK

can anyone met with this problem or knows a solution?
