[Valgrind-users] launching the app

[Xiang Y. <xy...@pr...>]

Hi all,

I failed to launch my app within valgrind, although it's successed =
before. here is the message:

=3D=3D29736=3D=3D valgrind-1.0.4, a memory error detector for x86 =
GNU/Linux.

srv_api.cpp @ 205: app starting...

VG_(get_memory_from_mmap): request for 34062336 bytes failed.
VG_(get_memory_from_mmap): 2124564464 bytes already allocated.

This may mean that you have run out of swap space,
since running programs on valgrind increases their memory
usage at least 3 times...

Here is what the top dumped:
CPU states:  0.0% user,  0.0% system,  0.0% nice, 100.0% idle
Mem:  2316656K av,  419432K used, 1897224K free,     440K shrd,  201724K =
buff
Swap: 2097096K av,   23640K used, 2073456K free                  132508K =
cached =20

I guess the swap space is large enough for running the app, any other =
clues?
(btw, here is the state of running my app without valgrind
