Hello; I have a VPS on which I serve Tomcat 6.0. 500mb memory was enough, when I had only two applications. Last week I deployed another web application and formed a new virtual host editing Tomcat server.xml. But the server responses slow down, linux started to eat the swap. When I increased the memory 750 mb it become stable again. Bu...
Hey guys, Let's put you this in context ;) Suppose you have a tableview that you can refresh. Would you keep the activityAnimator in memory or re-create it every time you click on refresh ... ? I know this could sound pretty obvious, it seems pretty clear that in the first case you get to speed up your app and in the other case you ge...
Well, the title says it. It would also be handy to know how many memory is still available. I am writing a memory hungry application that tends to crash randomly (in native Code), and my suspicion is that it gets out-of-memory. ...
Hi, Here is my code, which creates 2d array filled with zeros, array dimensions are (795,6942): function zeros($rowCount, $colCount){ $matrix = array(); for ($rowIndx=0; $rowIndx<$rowCount; $rowIndx++){ $matrix[] = array(); for($colIndx=0; $colIndx<$colCount; $colIndx++){ $matrix[$rowIndx][$colIndx]=...
I found my program have a memory leak when I used connectTCP. <class 'twisted.internet.tcp.Client'> <<class 'twisted.internet.tcp.Client'> to ('10.25.76.117', 8086) at 2066c5b0> <type 'dict'> {'_tempDataBuffer': [], 'protocol': None, '_tempDataLen': 0, 'realAddress': ('10 <type 'tuple'> ('10.25.76.117', 8086) <type 'list'> ...
I want to create some memory to use for DMA transfers. (Using Linux 2.6.18-128.el5 #1 SMP) I have a API stack+kernel driver for my H/W that can do this for me, but its very very slow! If I use the API to create a DMA transfer, it allocates some memory very high up in System RAM (eg 0x7373a6f8 on one run). (I have the ICD of the device,...
I'm writing a linux deamon and as for now it works pretty well, but it leaks memory ( and it's bad - after few hours it segfaults after using 60% of the system's memory). The strange thing is, that I'm using only new/delete operators and have a try/catch block around the main function, so it's not an exception thrown by new - it just seg...
Here's my situation. I want an explanation of why this is happening. I am reading about GC here but I still don't get it. Workstation case: When I run with workstation garbage collection, my app ramps up to use about 180MB of private bytes and about 70MB in ".NET CLR Memory #bytes in all heaps". Memory continues to be stable for seve...
We are using DevPartners boundchecker for detecting memory leak issues. It is doing a wonderful job, though it does not find string overflows like the following char szTest [1] = ""; for (i = 0; i < 100; i ++) { strcat (szTest, "hi"); } Question-1: Is their any way, I can make BoundsChecker to detect this? Question-2: Is their ...
I'm using DOMPDF to generate about 500 reports from one script. It's running out of memory after about 10-15 PDFs have been generated. In debugging, it looks like it's loading 8M every time it gets to the font loading stuff, but this seems like something that should be handled with the font caching code. Any ideas of what's going wrong...
It seems whenever there are static objects, _CrtDumpMemoryLeaks returns a false positive claiming it is leaking memory. I know this is because they do not get destroyed until after the main() (or WinMain) function. But is there any way of avoiding this? I use VS2008. ...
Hello I would like to find out what is the total heap size that is in use at a certain time by a Java process and I have to use jmap. The output of jmap -heap <pid> gives me something like this: Attaching to process ID 2899, please wait... Debugger attached successfully. Server compiler detected. JVM v...
I have read about this function didReceiveMemoryWarning that actually hasn't really helped. I would like to show a UIAlert View to tell the user that the action he is about to take will lead to problems with memory. So apart from crashing, which is a nasty way to inform the user that there is a memory Warning received, is there a possi...
Is that "the sum of all objects allocated" or is it "amount of memory allocated from the operating system for storing objects". Or is it something else? I think it is memory allocated from the OS, but would like a confirmation. ...
I've got a problem with a NSString in my app. I've defined it in the header file of my view controller. NSString *locationCoordinates; and I set its value in a -(void) method. - (void)locationUpdate:(CLLocation *)location { <...> NSArray *locArray = [locString componentsSeparatedByString:@", "]; NSString *xCoordinat...
void f() { char *c = "Hello World!" } Where is the string stored? What's the property of it? I just know it is a constant, what else? Can I return it from inside of the function body? ...
I have a simple program that breaks a dataset (a CSV file) into 4 chunks, reads each chunk in, does some calculations, and then appends the output together. Think of it as a simple map-reduce operation. Processing a single chunk uses about 1GB of memory. I'm running the program on a quad core PC, with 4GB of ram, running Windows XP. ...
