Hi All,
I'm eval'ing Wordperfect-7.0-for-Linux on `FreeBSD 3.0-971012-SNAP' and am
seeing lots of zombies:
1446 ?? Z 0:00.00 (xwpthes)
1460 ?? Z 0:00.00 (xwpgmk5)
1461 ?? Z 0:00.00 (xwpspell)
1462 ?? Z 0:00.00 (xwpspell)
1467 ?? Z 0:00.00 (wpp7)
1471 ?? Z 0:00.00 (xwpspell)
1472 ?? Z 0:00.00 (xwpspell)
1473 ?? Z 0:00.00 (xwpspell)
1513 ?? Z 0:00.00 (xwpthes)
1514 ?? Z 0:00.00 (xwpthes)
1531 ?? Z 0:00.00 (xwpthes)
1532 ?? Z 0:00.00 (xwpthes)
1533 ?? Z 0:00.00 (xwpthes)
1543 ?? Z 0:00.00 (xwpthes)
1551 ?? Z 0:00.00 (xwpthes)
As I understand, the root cause is that (xwp) is failing to reap dead children.
However, the children *do* get reaped when I exit xwp... it seems that
as long as xwp is running, no reaping is done, and the zombies accumulate...:(
What I'm wondering is:
i. Is this a fault/feature of the app (xwp), the linux emulation code, or
the kernel (in a larger sense), and
ii. are there any *good* workarounds. ( I seem to recall some discussion about
a tunable kernel parm for auto-reap or some such thing? )
Cheers,
Andrew.
