[Build 118] various problems with the optimizer and restarting SQX

Hello,

SQX:
- The speed of the optimizer is sometimes very slow (23% utilization of the cpu)
- Optimizer sometimes does not load strategies (capacity reachead) but memory capacity is about 30% full
- There is an error indicating that too little memory is available even though the memory capacity is about 30% full
- When restarting SQX, SQX stops at 3 of 4 reboots. Here, SQX 1500 is designed to load strategies - but there are often problems.

=> I going to reinstall then the errors are mostly eliminated and SQX runs for a few weeks again but that can not be the solution.

You get some files as attachment as well as the log files of today.

tank you for your report, we are looking at it.


Memory - from your screenshot I can see that your max. memory is 16 GB, even thought you have configured 50 GB in the settings. This is one of the reasons why SQ fails to load all the strategies.

Can you please attach here your file StrategyQuantX_nocheck.config so I can check if the configuration was written there?

Attachment StrategyQuantX_nocheck.config added

Memory - is phisically 64 GB; At present, the set 50 GB are also used.

The nocheck.config is attached.

ok, your settings work, I can see in the Heap memory chart that there is 50 GB maximum. Does it still cause problems when loding strategies because of small memory?

50 GB of memoy is enough to run the builder and the Optimizer and it is enought memory to load 1500 strategies. The duration of loading is up to 15 minutes.
