I'm developing a very thread intensive program on Linux 2.0 (pthread
1.60beta5) and I noted that it is very memory hungry. I checked all the code
to find if I forgot to dealocate something but everything seens right. So,
I wrote a small program to figure out if the problem is the pthread library.
If you run this program (with a TOP utilitie on another window) and you go
pressing ENTER you could note the process will increase its memory usage.
I'm missing something or the library has problems dealocating the memory
used by the theads ??
The tiny program is:
------------------------------
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>
void * do_nothing(void *)
{
char msg[1000]; /* only for test storage allocation */
puts("Executed...");
pthread_exit(0);
return NULL;
}
void main(void)
{
pthread_t thread;
char c;
while(1) {
c = getchar();
if (pthread_create(&thread, NULL, dummy, (void *)0xdeadbeef))
puts("Error: creating new thread");
}
}
-----------------------------------------
Any clues ??
please send mail to bellezi@vway.com.br
