While running my application in server, an error is thrown:
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 46900 bytes)
If anyone overcame my problem in experience, please help me.
Is 134 megabytes a reasonable amount of memory for your application to be using? If so, see if there is an option on the server to raise the maximum-memory-used limit. If not, figure out why your application is using so much RAM. Perhaps it has a memory leak?

I am trying to debug an embedded application with Valgrind.
Unfortunately, this application behaves differently than when I run it without Valgrind. At one point a driver allocates a data block of about 4 MB. This allocation fails even though there is still about 90 MB of memory available. Could it be that Valgrind fragments the memory so much that no contiguous block of that size is available anymore?
Does anyone have an idea how to remedy this?
We are running Operfire version : 3.9.1 on Windows 2008 R2 server in a 64 bit JVM.
Very recently , we have started seeing frequent CPU spikes on the server. The threads that are taking up most of the CPU time are blocked on this offset in
JVM -
jvm!JVM_FindSignal+2d7d
We are not seeing any out of memory exceptions. Also the CPU spike is generally seen during non peak hours. As a first resolution for this issue we recently increased the max heap memory from 1024mb to 2048mb but that seems to have made spikes more frequent. The server has total of 8gb memory out of which more than 4gb is free.
Please see attached screenshot for JVM version.
Any idea what this offset refers to ? We are not sure what is stressing the CPU so much and if this is an indication of a problem that can get bigger.
Any help is much appreciated
jvm!JVM_FindSignal is internal function inside JVM library that listens the signal from native operating system and returns to Java.
Signal can be (SIGABRT, SIGFPE, "SEGV", SIGSEGV,SIGINT,SIGTERM,SIGBREAK,SIGILL)
We need to inspect vmstat and iostat information to actually figure out the actual issue.
You can file issue to http://bugreport.java.com/ with vmstat and io stat information we will get back to you.
You are using JDK 8 update 91. Please upgrade to latest version JDK8 update 112.
I have several processes (JVMs) that are using huge amount of memory.
I'm starting the JVM with no -Xms value and with 2G or 3G in -XmX.
heap is stable and doesnt seems to have any leak or other issues. GC works perfect...
But... the process size and the VIRT value are huge. most are 10G-15G and even one is 20G !!!
Java used is 1.7 and working on VM installed with RH linux 6.5
I understand that the process size will be higher then the heap size as there is more than just objects :) but I've never seen such a huge addon...
Any idea what might cause that? any idea how we can reduce it?
Thanks a lot!

I have 16GB RAM and 64bit windows operating system.I want to run an web application I got heap space exception if i change VM arguments to -Xms3512m -Xmx3512m -XX:MaxPermSize=128m -XX:-UseGCOverheadLimit -XX:ReservedCodeCacheSize=32m I got exception as
Error occurred during initialization of VM
Could not reserve enough space for object heap
but I have another system with same configuration but that system accept this VM Arguments. please give me solution
Increase the heap size with: XX:MaxHeapSize=??m
Heap allocation done at the JVM initialization. It look for contiguous memory space of size -Xmx. If it could not find the continuous space of Xmx size then JVM failed during initialization Please add the argument -verbose:init and check the console output to identify which stage it failed on initialization.
Require urgent help!:(
i m developing a game and i m dealing with around 20 images at the same time.
As per my knowledge, i m allocating and deallocating the images at right places.
Game runs for around 15 min fine but quits with an error message:
"Program received signal: “0”. warning: check_safe_call: could not restore current frame"
i also tried debugging with memory leak tools provided in Xcode but could not find any issue with memory management or any increase in memory size
on simulator it works fine but not on the device.
i m confused wht can be the issue.
Any help is appreciated.
Thanx in advance
If gdb cannot restore the current frame, your stack is probably broken. This can result from huge stack allocations, e.g. a huge array/struct in a local variable.
If you don't find the problem, try enabling message logging (described here). Then you'll find the last valid method call at least.
