Service thread inactive for 0.00s
by Thomas Roth
Hi all,
what are the possible origins of messages of the type
> Apr 2 07:28:42 kernel: Lustre: Service thread pid 10573 was inactive for 0.00s. The thread might be
hung, or it might only be slow and will resume later. Dumping the stack trace for debugging purposes:
> Apr 2 07:28:42 kernel: Lustre: Service thread pid 10573 completed after 0.00s. This indicates the
system was overloaded (too many service threads, or there were not enough hardware resources).
> Pid: 10573, comm: ll_ost_92
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?
Regards,
Thomas

Hi all!
What kernels will lustre 2.4 support? If minimal version will be 2.6.32 many
cleanups and code symplifications can be done in master. Are there any plans
for it?
