This is a cryptographically signed message in MIME format. --------------ms080405080609090001080005 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Under fairly heavy stress (~50% of the 100Mbps possible FDX performance) I've now run into a problem that is turning into something I can repeat without too much trouble by transmitting a large file through the device.= The system appears to "crash" from the outside. It's not dead, however -- it's got some sort of network buffer hang going on. This is a Pi3 with current (-HEAD, FreeBSD 12.0-CURRENT #0 r318193M: Thu May 11 16:18:20 CDT 2017) software on it -- reverting to a mid-March kernel did NOT change the behavior. The symptomology is that the unit will start printing this on the console= : May 12 12:25:46 IPGw dhcpd: send_packet: No buffer space available May 12 12:25:46 IPGw dhcpd: dhcp.c:3974: Failed to send 300 byte long packet over ue0.3 interface. ue0.3 is a VLAN for a private subnet and is not specific to the issue; it also complains about no space on the primary too: May 12 12:27:06 IPGw dhcpd: dhcp.c:3974: Failed to send 300 byte long packet over ue0 interface. May 12 12:27:13 IPGw dhcpd: send_packet: No buffer space available netstat -m does /not /show any denied or delayed requests for network buffers or mbuf exhaustion. Systat -vm shows plenty of RAM available (roughly half.) An ifconfig ue0 down / ifconfig ue0 up sequence from the console clears the hang. Has anyone else seen anything similar to this? --=20 Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/ --------------ms080405080609090001080005 Content-Type: application/pkcs7-signature; name="smime.p7s" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="smime.p7s" Content-Description: S/MIME Cryptographic Signature MIAGCSqGSIb3DQEHAqCAMIACAQExDzANBglghkgBZQMEAgMFADCABgkqhkiG9w0BBwEAAKCC BlwwggZYMIIEQKADAgECAgE9MA0GCSqGSIb3DQEBCwUAMIGQMQswCQYDVQQGEwJVUzEQMA4G A1UECBMHRmxvcmlkYTESMBAGA1UEBxMJTmljZXZpbGxlMRkwFwYDVQQKExBDdWRhIFN5c3Rl bXMgTExDMRwwGgYDVQQDExNDdWRhIFN5c3RlbXMgTExDIENBMSIwIAYJKoZIhvcNAQkBFhND dWRhIFN5c3RlbXMgTExDIENBMB4XDTE2MTIxODE5NDUzNVoXDTIxMTIxNzE5NDUzNVowVzEL MAkGA1UEBhMCVVMxEDAOBgNVBAgTB0Zsb3JpZGExGTAXBgNVBAoTEEN1ZGEgU3lzdGVtcyBM TEMxGzAZBgNVBAMUEmthcmxAZGVubmluZ2VyLm5ldDCCAiIwDQYJKoZIhvcNAQEBBQADggIP ADCCAgoCggIBAM2N5maxs7NkoY9g5NMxFWll0TYiO7gXrGZTo3q25ZJgNdPMwrntLz/5ewE9 07TEbwJ3ah/Ep9BfZm7JF9vTtE1HkgKtXNKi0pawNGm1Yn26Dz5AbUr1byby6dFtDJr14E07 trzDCtRRvTkOVSBj6PQPal0fAnDtkIYQBVcuMkXkuMCtyfE95pjm8g4K9l7lAcKii3T1/3rE hCc1o2nBnb7EN1/XwBeCDGB+I2SN/ftZDbKQqGAF5q9dUn+iXU7Z/CVSfUWmhVh6cVZA4Ftv TglUqj410OuPx+cUQch3h1kFgsuhQR63HiJc3HbRJllHsV0rihvL1CjeARQkhnA6uY9NLFST p5I/PfzBzW2MSmtN/tGZvmfKKnmtbfUNgkzbIR1K3lsum+yEL71kB93Xtz/4f1demEx5c8TJ RBIniDHjDeLGK1aoBu8nfnvXAvgthFNTWBOEoR49AHEPjC3kZj0l8JQml1Y8bTQD5gtC5txl klO60WV0EufU7Hy9CmynMuFtjiA2v71pm097rXeCdrAKgisdYeEESB+SFrlY65rLiLv4n8o1 PX7DqRfqKkOYIakZ0ug/yHVKcq2EM3RiJxwzls5gT70CoOBlKbrC98O8TA6teON0Jq30M06t NTI2HhvNbJDLbBH+Awf4h1UKB+0ufENwjVvF5Jfz8Ww/FaSDAgMBAAGjgfQwgfEwNwYIKwYB BQUHAQEEKzApMCcGCCsGAQUFBzABhhtodHRwOi8vY3VkYXN5c3RlbXMubmV0Ojg4ODgwCQYD VR0TBAIwADARBglghkgBhvhCAQEEBAMCBaAwCwYDVR0PBAQDAgXgMCwGCWCGSAGG+EIBDQQf Fh1PcGVuU1NMIEdlbmVyYXRlZCBDZXJ0aWZpY2F0ZTAdBgNVHQ4EFgQUpfAI3y+751pp9A0w 6vJHx8RoR/MwHwYDVR0jBBgwFoAUJHGbnYV9/N3dvbDKkpQDofrTbTUwHQYDVR0RBBYwFIES a2FybEBkZW5uaW5nZXIubmV0MA0GCSqGSIb3DQEBCwUAA4ICAQBiB6MlugxYJdccD8boZ/u8 d8VxmLkJCtbfyYHRjYdyoABLW5hE3k3xSpYCM9L7vzWyV/UWwDYKi4ZzxHo4g+jG/GQZfKhx v38BQjL2G9xD0Hn2d+cygOq3UPjVYlbbfQoew6JbyCFXrrZ7/0jvRMLAN2+bRC7ynaFUixPH Whnj9JSH7ieYdzak8KN+G2coIC2t2iyfXVKehzi5gdNQ0vJ7+ypbGsRm4gE8Mdo9N/WgFPvZ HPFqR9Dwas7Z+aHwOabpk5r/336SyjOaZsn3MqKJQZL6GqDKusVOCWt+9uFAD8kadg7FetZe atIoD9I+zbp59oVoMnkMDMx7Hi85faU03csusqMGsjSsAzWSI1N8PJytZlchLiykokLKc3OL G87QKlErotlou7cfPX2BbEAH5wmkj9oiqZhxIL/wwAUA+PkiTbEmksKBNompSjUq/6UsR8EA s74gnu17lmijv8mrg2qMlwRirE7qG8pnE8egLtCDxcjd0Of9WMi2NJskn0/ovC7P+J60Napl m3ZIgPJst1piYSE0Zc1FIat4fFphMfK5v4iLblo1tFSlkdx1UNDGdg/U+LaXkNVXlMp8fyPm R80V6cIrCAlEWnBJNxG1UyfbbsvNMCCZBM4faGGsR/hhQOiydlruxhjL6P8J2WV8p11DdeGx KymWoil2s1J5WTGCBRMwggUPAgEBMIGWMIGQMQswCQYDVQQGEwJVUzEQMA4GA1UECBMHRmxv cmlkYTESMBAGA1UEBxMJTmljZXZpbGxlMRkwFwYDVQQKExBDdWRhIFN5c3RlbXMgTExDMRww GgYDVQQDExNDdWRhIFN5c3RlbXMgTExDIENBMSIwIAYJKoZIhvcNAQkBFhNDdWRhIFN5c3Rl bXMgTExDIENBAgE9MA0GCWCGSAFlAwQCAwUAoIICTTAYBgkqhkiG9w0BCQMxCwYJKoZIhvcN AQcBMBwGCSqGSIb3DQEJBTEPFw0xNzA1MTIxNzQ1MjhaME8GCSqGSIb3DQEJBDFCBECUEIXq 8ahK+eNTN+rf9053Micgf7b9e7qpbnC/P1OCkW0ddn9ErZdw9L5rfAtoIE1FT2HEaa7gEoWE rSQUL2D4MGwGCSqGSIb3DQEJDzFfMF0wCwYJYIZIAWUDBAEqMAsGCWCGSAFlAwQBAjAKBggq hkiG9w0DBzAOBggqhkiG9w0DAgICAIAwDQYIKoZIhvcNAwICAUAwBwYFKw4DAgcwDQYIKoZI hvcNAwICASgwgacGCSsGAQQBgjcQBDGBmTCBljCBkDELMAkGA1UEBhMCVVMxEDAOBgNVBAgT B0Zsb3JpZGExEjAQBgNVBAcTCU5pY2V2aWxsZTEZMBcGA1UEChMQQ3VkYSBTeXN0ZW1zIExM QzEcMBoGA1UEAxMTQ3VkYSBTeXN0ZW1zIExMQyBDQTEiMCAGCSqGSIb3DQEJARYTQ3VkYSBT eXN0ZW1zIExMQyBDQQIBPTCBqQYLKoZIhvcNAQkQAgsxgZmggZYwgZAxCzAJBgNVBAYTAlVT MRAwDgYDVQQIEwdGbG9yaWRhMRIwEAYDVQQHEwlOaWNldmlsbGUxGTAXBgNVBAoTEEN1ZGEg U3lzdGVtcyBMTEMxHDAaBgNVBAMTE0N1ZGEgU3lzdGVtcyBMTEMgQ0ExIjAgBgkqhkiG9w0B CQEWE0N1ZGEgU3lzdGVtcyBMTEMgQ0ECAT0wDQYJKoZIhvcNAQEBBQAEggIApkoL8/gMDwxj PAO0M9038+/mxS+JMovCCHPXCEgYU3xK/U9zQ+M8KXjoqp78cjk05jbi1hSQiBdFkQehEWRd n9qxXTiQC5kF/ozVb0eJB0tWPXgYyWTwNSuTdfQGdF04JI209D1VK1twVLzTMVjFcVRRubJ1 TwT5owJGPLoOkYg6x63lvbB6Zhz7FzbSjfmwW1TFD/DEFkRTQfpYfbbyGOwdlS/XccoR5gY1 BR+fhHSf0N7GB0RRHFxw359xXPCHI4vJLoN3J6suq3phetNDFE6Ew6ihEMp0pApdJCpl7FJj G+a4NRXU0zrEDHZF2sdcW4bRGIVZF3IiKCWqAoA+Jn9FP3WGZ754tKCgpVautZguinW3iqqD 01Xq4BvlFqt1/mgnK0RSSGt0pGDK8brWyOPwWODuJBBDybadbRL+6iQflTr77O3nVQa2DuO6 0wgZl+33siVVIwBHPRfmg7twis1V9dct7ya9nunD7S9xAHY3vOjoci9ZoGYZOo3SYaaM9QQp vumIzSGdwkHogvdpgccRj2YCsVpAGgNHvzw8FhCVgcjZx8Kjhu02CIqhLJyBY1i2vn5DUVag cqZTuVt6XI/yPA7XU4d4IVKXY+qxcn/8tBPA20Fa149jRCMfGNW4C4l8NXTPJNVbc9P2CWwr GWgyd6osWElnnLxdlEiWq10AAAAAAAA= --------------ms080405080609090001080005--
