Hi,

 

i try to open a file.

 

I used the following code:

 

//malloc

char * buffer = (char*) Genode::env()->heap()->alloc(sizeof(char)*lSize);

FILE* pFile = fopen(fileName, "rb");

size_t result = fread (buffer,1,lSize,pFile);

fclose (pFile);

//free (buffer);

env()->heap()->free(buffer, 0);

 

The code seems to work if the file is quite small.

 

I try thre same with a file of size 128 MB. I have given rump_fs a quite large quota of 520M

 

uota exceeded! amount=69632, size=8192, consumed=65536

ould not allocate metadata

[init -> rump_fs] pgrading quota donation for Env::RAM (8192 bytes)

uota exceeded! amount=77824, size=8192, consumed=73728

ould not allocate metadata

[init -> rump_fs] pgrading quota donation for Env::RAM (8192 bytes)

[init -> rump_fs] lab-backend exhausted!

 

And from this point onwards only Slab-backend exhausted messages are shown.

 

Is there some max size for ram quotas?

 

Best regards,

Wolfgang
