flexmonster data server error IO

Hello, Nam!
 
Thank you for contacting us.
 
Kindly note that you can specify how much time the Data Server should wait for the query to execute by using CommandTimeout property.
For that, specify the time in seconds inside the flexmonster-config.json file as follows:

{
    "DataSources": [
       ...
    ],
    "DataStorageOptions":
    {
        "CommandTimeout": "5" //time in seconds
    },
}

 
You can read more about the CommandTimeout property in our docs: https://www.flexmonster.com/doc/configurations-reference/#CommandTimeout.
 
Please let us know if the suggested property was helpful for your case.
 
Looking forward to hearing from you.

Hello, Nam!
 
Thank you for your feedback.
 
We are glad to hear that the suggested CommandTimeout property was helpful.
 
Regarding "when use 8Gb memory container Flexmonster Data Server doesn't create the log file", please find the explanation of the Data Server memory usage below.
It seems to us that 8Gb of RAM is not enough for the Data Server to process the given amount of data.
The Data Server loads all data from the data source and keeps it in the RAM as well as all the aggregations to provide a quick response to every client's request. From our experience, Flexmonster Data Server tends to use 200%-300% of memory compared with the original data size.
 
When starting the Data Server, all logs should be shown in the terminal window. Could you please provide us with the terminal output when running FLexmonster Data Server on 8 Gb of RAM? 
This information would help us greatly to continue the investigation.
 
Looking forward to your response.
