Controller was not able to download and Heap memory was ~100%. Afte Powr retart it soled..What will be reason..?
In AC800M PM864, Controller was not able to download and Heap memory was ~100%.
After restart it downloaded and heap memory came to 39%.
What will be the reason for this..?
And we neve changed Safety level..!!
I have seen rare issues where the memory fragmented badly and leaked over many many downloads. A cold start resolved the issues. Is the controller faster to download now ?
There may not be much more that anyone can tell you now that the problem has cleared. However you should monitor the heap usage and log a support case if memory begins to creep again.
