On several FreeBSD machines I have the following problem:

Check top -H to display the statistics for individual threads.

This seems to be the only inconsistent one:
# ps -ax|grep 1079
1079 con- S 576:13.90 [mysqld]
Check that your ps binary is in sync with your kernel, i.e. rebuild
world with the same sources you used to build your kernel.
Kris
I did that. First, downloaded source with csup, built world, kernel,
installed kernel and world. Then rebuilt kernel once again and
installed it.
On another machine (w/ 32bit kernel):

=============^^^^
Here is the problem. top returns only 9:42 -- the time of the first
thread. ps returns the sum of the thread times, which is correct.
Best regards,
O.K.
21763 p0 R+ 0:00.01 grep 979
Well, that one makes sense, it's the sum of the thread run times. The
previous one you posted wasn't though - maybe you didn't paste in all
of the threads?
