Re: bug? mtu 9000 problems with iscsi target: msg#00236

Subject: Re: bug? mtu 9000 problems with iscsi target

As you might have guessed already, your machine is out of memory. Not
necessarily a (target) bug, I guess.

Makes sence in as much that the machine only had 256 MB memory, it's just a poor old P-II 350.

Maybe not a bug pur sang, but I would have expected the target not to gobble up all memory and wanting more without a decent error message. Since its buffer memory it is locked in memory, not to be swapped out (right assumption?), it can only allocate as much as there is (and slightly less as the OS wants some too).

The decent thing is to allocate only as much as there is (maybe limited also by a settable maxmem parameter) and not assume that it can allocate memory indefinitely. Even with lots of memory it will hit the wall sometime.

But I can not believe that there isn't any check on this in the target code.
