Hello everybody, based on the thread "[RFC] Migration to MariaDB" in arch-dev-public by Bartłomiej Piotrowski I started playing with MySQL and MariaDB. I noticed both were polling every second: <... futex resumed> ) = -1 ETIMEDOUT (Connection timed out) futex(0x1d48050, FUTEX_WAKE_PRIVATE, 1) = 0 gettimeofday({1361806174, 246573}, NULL) = 0 futex(0x1d4808c, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 2849, {1361806175, 246573000}, ffffffff <unfinished ...> Searching Google I found that the problem may be caused by the leap second, though the load is not as high as some articles describe. (Continues polling vs. one poll a second.) However the polling stops as soon as I manually set the time with date -s and it start again if I run ntpdate to sync the time. As this is a notebook I rebooted more than once since the leap second happened. ;) What is going on? This is a mobile system, so it would be great to get rid of mysqld eating my battery power. -- main(a){char*c=/* Schoene Gruesse */"B?IJj;MEH" "CX:;",b;for(a/* Chris get my mail address: */=0;b=c[a++];) putchar(b-1/(/* gcc -o sig sig.c && ./sig */b/42*2-3)*42);}
