On several FreeBSD machines I have the following problem:
What FreeBSD version? (It matters)
7.1-PRERELEASE FreeBSD
But I can experience it also on a 7.0 machine. Seems that top reports
incorrectly processes with multiple threads.

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.

# ps -aHx|grep 1079
1079 con- S 1:58.71 [mysqld]
1079 con- I 0:00.00 [mysqld]
1079 con- S 0:01.30 [mysqld]

1079 con- S 4:09.88 [mysqld]

Strange?
