Hello,
On our Opto22 S/N GRV-EPIC-PR1 757922, we had install the grv-epic-pr1-ignition8-3.3.3-b.192.field.bin version, which was supposed to improve the intempestive system reboot, and unfortunately, sometime, we saw ever some intempestive HW restarting (see the logs at 2022-06-15 16:42) without manual action.
It’s not possible to joint the log…
Can you explain and correct this bug?
Thanks in advance
In cases like this, the best thing to do is to send an email to our support team (support@opto22.com) and they can assist you in gathering the log files that our software engineers need to get to the heart of the issue.
Support will also be able to assign you a tracking number so you can have a reference for this problem solving process.
I would also suggest upgrading EPIC firmware to 3.4.0, as this increased the memory assigned for Ignition EDGE and also resolved some dodgy handling of Ethernet communication sessioneswhen communicating to other devices. Both of these could be leading to the PR1 restarting itself to get over memory problems. There are usually clues that this is happening in both groov-EPIC logs and Ignition EDGE logs, but as Ben says, you need to be an experienced support engineer to understand what the logs are reporting.
Although there is no fixed rule, In my opinion, running Ignition Edge 8.1 on a PR1, with large projects and especially if you are running other EDGE modules, may cause you to be running pretty low on memory, which in the end can lead to resets. In this case, you should at least be considering the use of a PR2.
