bad blocks cause glibc error

hi,

is it possible bad blocks cause glibc error in my qt app.

thanks

What makes you think there is a "bad block" in your NAND?

hi Juergen,

Thank you for your replay.
I have a qt app that must work 24/7. We installed this app on about 10
devices , after start this devices some of them works perfectly and some of
them works about 1 or 2 days and suddenly stop working  with a glibc error.
Surprisingly after restarting stopped devices, again, some of them works
with no error. This condition made me think about  hardware problem
especially  memory problem.

thanks.

What hardware you are using? Memory issues != NAND issues. Did you check
how the SDRAM-timings are setup in your hardware? Do all these devices
exactly the same? Could it be a memory leak in your app?

It's a really confusing problem. My devices are the same and there is no
any  memory  leak in my app but I don't have any idea about  SDRAM-timings.
By the way, I found a temporary solution for my  problem. I rum my app like
this:

MALLOC_CHECK_= 0 /myapp -qws

and everything is ok. Could you please tell me more about SDRAM-timings.

thanks.

Uhhhh, think a little bit about this workaround....if this helps, then your
application contains a bug, not your hardware.
