The last events in the alarm show this Quote MJE33 10/24/2019 18:04:41 RTG Restart C1-MP MJA04 11/20/2019 09:30:28 MCP Reset Watchdog MNF38 11/20/2019 09:30:28 Card Active C1-S01 MNF38 11/20/2019 09:30:28 Card Active C1-S03 MNF38 11/20/2019 09:30:28 Card Active C1-S04 MNF38 11/20/2019 09:30:28 Card Active C1-S05 MJA05 11/20/2019 09:30:28 LCP Restart CABINET:1 MJE01 11/20/2019 09:30:28 MGI Restart C1-MP MJE10 11/20/2019 09:30:28 SVMi Restart C1-MP MNF33 11/20/2019 09:30:28 SVMi Request C1-MP MNF22 11/20/2019 09:30:28 SIP INIT SUCCES MNF35 11/20/2019 09:30:28 SVMi Request End C1-MP MNF36 11/20/2019 09:30:28 SVMi HDD Alarm C1-MP 00% MJE14 11/20/2019 09:30:28 MPS Restart C1-MP MJE20 11/20/2019 09:30:28 OAS Start C1-S01 MJD24 11/20/2019 09:30:29 L2 Connect C1-S05 MJE33 11/20/2019 09:33:28 RTG Restart C1-MP However, the system rebooted a number of times before that. All the digital phones would boot up, work for 2 minutes, then shut off for about 2.5 minutes. I tried a manual power reset of the 7200 which didn't change behavior. I have pingplotter running on my network at all times to monitor uptime, and it shows the correlation between the mail server outage and the reboots Anyone know why this happens?

It was fixed in â€™16.03.08 V4.95 So if your mail server is down, and you're on this version, your system will keep resetting until the mail server can receive SMTP again. [Bug Fix] 14. [-/Linux/ALL] System restart after set DM 6.1.4 System Alarm Mail Server Info <Description> System restart after set Send Day and Send Major Alarm Immediately on DM 6.1.4 System Alarm Mail Server Info because of failure of socket control <Cause> In this case, there is a failure of tcp socket control <Resolution> checking tcp socket validation.
