hi
since july 1st 00:00 2012 I’ve seen high cpu load due to some java app. In my case it was the adaptec storage agent.
strace -p
showed me some problem with the realtime clock
futex(0xFUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME,ETIMEDOUT (Connection timed out)
Clock: inserting leap second 23:59:60 UTC
dmesg showed me this output
you don’t have to restart any serivce
just run the following:
/etc/init.d/ntp stop date `date +"%m%d%H%M%C%y.%S"` /etc/init.d/ntp start
so due to an leap second all machines running adaptec storage_agent got high cpu load :-(
