Hi Liviu, Thanks for your answer!
I am still somehow trying to relate this to the rest_client problems context as it happened in exact same time (the errors have not been oberved in other situations even with higher traffic). I do not know internals of OpenSIPS - but is it possible that this is somehow related to receive buffers ? That is, OpenSIPS threads are busy waiting for rest_get responses (which have long delays) which leads to slow processing of incoming traffic and hence these errors ? Or is this not related in any way?
