What kernel version is this? In the latest
fs/nfsd/vfs.c:nfsd_racache_init(int cache_size):
raparml = kcalloc(cache_size, sizeof(struct raparms), GFP_KERNEL);
if (!raparml) {
printk(KERN_WARNING
"nfsd: Could not allocate memory read-ahead cache.\n");
return -ENOMEM;
}
which is called from fs/nfsd/nfssvc.c:nfsd_svc() as:
error = nfsd_racache_init(2*nrservs);
where nrservs is the number of server threads. How many server threads are you
trying to start, and how much memory do you have?
