Paul Sandys commented on ASTERISK-25793:
----------------------------------------
It seems it's related to the chan_sip thread unable to process the UDP packets quick enough and they start dropping out of the system UDP buffers.
LInux UDP packet receive errors counter increases dramatically under load.
Before 'sip reload':
#netstat -s -u
Udp:
90610147 packets received
560701 packets to unknown port received.
376701 packet receive errors
82532640 packets sent
After 'sip reload':
Udp:
90673068 packets received
560705 packets to unknown port received.
387273 packet receive errors
82605540 packets sent
