[OpenSIPS-Users] ERROR:load_balancer:do_load_balance: failed to create dialog

[Peter P GMX]

After upgrading Opensips from 1.5.3 to 1.6.2 we get the following errors:
  ERROR:load_balancer:do_load_balance: failed to create dialog

Googling this error showed no results. Any hints where this comes from?

here's the (anonymized) config file:
