Redis continuously takes a large amount of memory and grows until killed by OOM -

-

Currently, my 8GB RAM server is using 5.33 GB for radis (approximately 1.6 in other parts of the server) GB, so even after the reboot of the server, I already have ~ 7 GB RAM [88%]). The memory usage of the REDIS continues to grow until it is ultimately killed by the OOM of Ubuntu, causing the nervousness of errors for my node application.

I've attached Radis Info Output at the bottom of this post. I originally thought that redis could be a lot of keys, but I read from REDIS () that 1 million keys are ~ 100 MB, we have around 2 million (~ 200 MB - nowhere near 5GB) , So this could not possibly be a problem.

My questions are: - When is all this memory consuming? The keyspace does not take much at all. - What can I do to stop it from taking more storage?

Thank you!

Thanks for the response Itamar I was under the lie (and does not seem really enough) After the assumption that the keys and value will almost all have the same size -

Turns out that some swans were collected from there, which were more than every 10KB, and we had hundreds of thousands Worked out by removing those people.

Thanks again.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
