Unix Error Cannot Perform Malloc

Can't figure out why it segfaults-1Please help me figure out malloc issue3simple 4-line C program with massive malloc only segfaults with Valgrind0Program exits after calling malloc145Why does the Book say I Dispite me being able to show at-hoc, the typically VERY large amount of local node memory requests on top of the remote node (underscoring the obvious performance throughput advantage), you can Whether that is actually significant in your application or not depends on several factors and you should profile the application with actual data before turning to such optimizations. I would like to handle malloc failure as well, I can I do that? have a peek here

Another error source is, I think, writing outside the allocated object (because bookkeeping information is stored between the "officially" allocated blocks which gets destroyed and sends malloc into the nether). Hands down; real world, fake world, whatever world... Before I leave my company, should I delete software I wrote during my free time? but maybe you should post the part of the interesting code here and someone will certainly point the problem (not me hehe i don't know c++)...

For debugging this kind of error with gcc you may find gnu.org/software/libc/manual/html_node/… interesting, or this SO question: stackoverflow.com/questions/1010106/… (with helpers in Win and *nix). –Peter A. The situation has only improved since then. The answer may surprise you -- allocation in modern JVMs is far faster than the best performing malloc implementations.

  8. You can take this figure as an upper bound, i personally feel that a typical application spends more like 10-15% of execution time allocating/deallocating memory.
  9. Edit: Although I mention malloc, this question is not intended to be C/C++ specific.
  10. But if you think your program is important and allocation fails later on, then sleeping and retrying seems like a good idea to me.

The default allocation strategy is OK for most cases but it can be changed to suit whatever is needed. All rights reserved. Mulligan Information forwarded to [email protected], Helmut Geyer : Bug#47452; Package xxgdb. NUMA aware memory request/use technologies are faster.

Can you still reproduce this problem with a current potato system? And that is why whe have new Collector params, and new collectors for new Java machines.

The JVM allocates and deallocates large chunks of memory in one go. A malloc in C/c++ is much more expensive, just because it has to do more work. Browse other questions tagged c graph io malloc stdio or ask your own question. This allows multiple threads to make allocations simultaneously so that exclusive access to the heap is not required." –Zan Lynx Jun 4 '09 at 6:03 Actually, modern memory allocators

If your application asks for more memory than the system has then the malloc will fail, no matter what. navigate here Garbage collection may affect the performance of your application significantly since user threads must be suspended during compaction of memory.

Full text and rfc822 format available. There are basically two situations when a memory allocation fails: 1) Either other programs use more memory than they should, bothering your program with their greed. My guess is 5-20 % is where 95 % of applications would be. –Suma Jul 6 '09 at 9:38 add a comment| up vote 0 down vote Others have covered C/C++

Looking at the xxgdb code that happens inside a library (it doesn't mmap itself), so it might not even be xxgdbs code. Note: I'm not talking about real-time stuff here.

Generally if you have a lot of memory reference the garbage collector will have to do more work. E.g. what kernel are you running? If the relation between them is simply a definition like Node nodeObj; then it shouldn't matter whether you use the type or the object. @alk: How does nulling the pointer help?
