Hi,
I'm experiencing a problem with OpenSips,
after a while that the server is up, OpenSips log start cyclically log the following messages:

Jan 12 21:17:21 [25355] CRITICAL:core:io_watch_del: invalid fd 1415934569, not in [0, 32)
Jan 12 21:17:21 [25355] DBG:core:handle_tcpconn_ev: data available on 0xb60c7e28 1415934569
Jan 12 21:17:21 [25355] CRITICAL:core:io_watch_del: invalid fd 1415934569, not in [0, 32)
Jan 12 21:17:21 [25355] DBG:core:handle_tcpconn_ev: data available on 0xb60c7e28 1415934569

OpenSips (and the connected WeSip) continue to work properly.
Do you know what this log are about?How to fix it?

Thanks in advance,
Antonio
