[sr-dev] Memory fragmentation

We now seem to be experiencing problems with Kamailio running out of memory after a period of time running our soak test. After dumping the shared memory I can see that there is no memory leak, but the problem is that memory is hugely fragmented with all the free blocks being less that 10k in size, which is too small for the tcp buffer it is trying to allocate memory for. We've noticed that there is a new kamailio runtime option mem_join that by default is 0. Was the previous default dehaviour the equivalent to this being set to 1? Thanks Paul
