[HPDD-discuss] Service thread inactive for 0.00s

Hi all, what are the possible origins of messages of the type hung, or it might only be slow and will resume later. Dumping the stack trace for debugging purposes: system was overloaded (too many service threads, or there were not enough hardware resources). Apart from taking the enormous 0.00sec, these threads were running on an unused test system, Lustre v 1.8.9_intel. And at the given time, it was isolated in its own IB-subnet, all other traffic was cut because of a general failure of the surrounding network ;-) Each of these messages is accompanied by a trace. I'm quite accustomed to seeing such messages, but then they appear on the heavily used production system, the times given are ~ 1000s, and the overload of the respective box is quite visible, too. But here?
