We have to following configuration

a BM 3.8 VPN Master talking to 3 BM 3.5 SKIP slaves.

Our internet connection is 2Mb
The VPMASTER_THREAD is massively busy and bringing the system utilization up
to between 88 & 90% constantly.

Has anyone got any ideas how we might fix this.

Patch levels.

NW 6.5.3
+ BM3.8sp3
