Package: procps Version: 1:3.2.7-5 Severity: normal
The start times of processes as reported by ps fluctuates occasionally. The following command line shows differences in consecutive ps invocations, each 1 s apart. /proc/1721/stat field 19 shows a constant start time of 6143 jiffies since boot for the mysqld process. The start time shown by ps fluctuates between 12:13:26 and 12:13:27 and the start times for (all?) other processes fluctuates by the same amount (1 s). This bug may be related to the other time related bugs of ps. s:~# while true ; do mv x2 x1 ; uptime ; cat /proc/1721/stat ; ps axww -o user,pid,start,ni,stat,cp,vsz,rss,%mem,comm --sort -vsz|head -n
