[124] SQX Crash black screen
I meet the issue about crash with SQX.
In this process I run 2 projects and optimizer together.
I find that maybe about the CPU usage over the setting
I setting 5 cores for SQX use(totaly 8 cores)
But it still also use more than 5 cores cpu when project are running MC.
And it will happen error " cannot create indicator" on the log.

Most probably running all the projects and optimizer at once exhausted all available memory, you should change your cofiguration, run less things in parallel, or increase amount of RAM for SQ.
When you have memory problems please check Heap chart sometimes when SQ is running.
Green area is your total allocated memory - this is the number you see also in Task manager.
Red area is actually used memory - it is fluctuating as objects in memory are created and deleted.
When you use full available memory (green area is up to the top) the red area shouldnt be more than 70-80% of the whole memory. So for example, if you have 16 GB allocated for SQ, your actual usage (red area) shouldn't be bigger than 12-13 GB.
If it is bigger it means SQ doesn't have enough free memory for its operations and you either have to increase memory or change your configuration.

So, maybe the crash is not with memory, it is cause by testfile like this topic

10.10.2019 13:52Most probably B 124 uses CPU more effectively than B 122, which means it is running more jobs in parallel, or more things insie de one job, and that is why it also takes more memory.

10.10.2019 16:21OK, I see.
But, is it possible to control the cpu useages situation with the setting? because it maybe it is the one of reasons with crash.
Thank you.

How much memory do you have configured for SQ?
It looks like it could be caused by SQ using too much memory.
