[asterisk-users] couldn't allocate a port for RTP instance

[Fourhundred Thecat]

Hello,

my logs are flooded with:

WARNING: The 'stasis/m:cdr:aggregator-00000005' task processor queue
reached 5000 scheduled tasks again.

and then, when call came, I got this:

ERROR: Oh dear... we couldn't allocate a port for RTP instance
'0x6e1e680fd670'

WARNING: Unable to cancel schedule ID 0.  This is probably a bug
(res_rtp_asterisk.c: dtls_srtp_stop_timeout_timer, line 2873).

any idea what is happening, or how to troubleshoot his ?
