top incorrectly reporting process time

[Ott Köstner]

Hello,

On several FreeBSD machines I have the following problem:

# top -bUmysql
last pid: 99112;  load averages:  0.22,  0.12,  0.09  up 2+06:07:05
16:17:43
132 processes: 1 running, 131 sleeping

Mem: 718M Active, 2494M Inact, 455M Wired, 77M Cache, 214M Buf, 213M Free
Swap: 4096M Total, 4096M Free


  PID USERNAME      THR PRI NICE   SIZE    RES STATE  C   TIME   WCPU
COMMAND
1079 mysql           9  20    0 81564K 60268K sigwai 1   0:01  0.00% mysqld
 

^^^^^^^
------------------------------------------------------------------------------------------------------------

1015 mysql           1   8    0  7056K  1368K wait   1   0:00  0.00% sh


However mysqld time is actually

# ps -ax|grep mysql
1015 con- I      0:00.01 /bin/sh /usr/local/bin/mysqld_safe
--defaults-extra-file=/var/db/mysql/my.cnf
1079 con- S     70:03.64 [mysqld]
                       ^^^^^^^^^^^
------------------------------------------------------------------------------------------------------------

99156  p0  S+     0:00.00 grep mysql

Anyone who can explain this?

With greetings,
Ott Köstner
