(last one;) To make it cease and desist starving your box, renice the shell you're running irman from. 12 is the magic (hmm) number here at which starvation ceases. It's interesting to watch the response times irman reports. The higher the renice level, the better response times it reports both in 2.5.64-virgin, and 2.5.64-combo (which looks like what is in bk2). /me has no clue whether that means anything or not ;-) ciao, -Mike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
