Irregular system failures

Tompanhuhu

I'm running a 1300 robot with RW 7.1.0 and get system failures very often.
I get no errors in the log.
I have sent system diagnostic files to the robotsupport team in Sweden without any response.

I have checked the system diagnostic file and found the following logs.

{args: "MC0: mchException.c 112 (tMchExc): SYS FAIL Exception: task: "servots0", vecNum: 14 (Page Fault), pc: 0x8bbbb246, cr2: 0x00000018 "}

Is there anyone that can help me pinpoint a issue or find a workaround?

Anyone else with similar issues?

Hi, I have a similar problem and also not obtaining any specific answer about it from the local support.
On 2 different robot IRB1300 with Omnicore controller, installed on 2 different machines, I have irregular system failures and the only information that I can retrieve from the SysDiagnostic is -> MC0: mchException.c 112 (tMchExc): SYS FAIL Exception: task: "CMCTL_STATE", vecNum: 14 (Page Fault) pc: 0x8a1802bf cr2: 0xeeeeeeee   
The robots in each machine are the Profinet Controller of the machine and 3 Profinet devices are installed and controlled by each IRB1300.
The error usually occurs after 6 hours from the power on and it doesn't depend from what the robot is doing. I can leave the robot in emergency state for 6 hours and then see the error. The only thing that runs is a parallel task that does simple control on inputs like a normal PLC.
We've seen this problem on RW7.6.0 and also on RW7.6.1
Any help is appreciated.
