Hi Bogdan.
I have the same problem as Douglas, but to apply resolve.c patch don't solve the problem. I'm using version 1.1.0.
Memory debug info is available at http://vorigon.com/mhack/openser/ the problem occur only in threads 23208, 23209, 23210 and 23211.
I stopped the load during 1 hour but when I restarted the problem came back to happen in the same threads.
My configuration file is in the same location.
Regards,
Marcos Hack.
