Nathan,

Thanks a lot for a good explanation.

At the moment we are using 4Gb of memory on this machine. Do you think, it will help if I add more memory ?

And, you said it tries to allocated memory a number of times. Is it in support/kmem.c file : #define MAX_SHAKE 8 ?
May be I can try to increase this value.



The fact that you have 4G of memory and you are running out is not a good thing. Unless you have some application which is locking down huge chunks of memory, you should not be able to run something this large out of memory.

Taking a look at where the memory is on the system would be a good
thing to do.

Steve
