[vpsFree.cz: community-list] Zombie procesy

[Stanislav Petr]

Cau,

po dnesnim vypadku node5 pozoruji v systemu problem se zombie procesy.
Stava se to jeste nekomu?

ps ax | grep Z
 2567 ?        Z      0:00 [/usr/libexec/mu] <defunct>
 2583 ?        ZNs    0:00 [asterisk_sipcha] <defunct>
 2651 ?        ZNs    0:00 [asterisk_channe] <defunct>
 2828 ?        Z      0:00 [/usr/sbin/apach] <defunct>

Zatim nevidim zadnou souvislost.

Proces 2567 je perl script (perl 5.20.2, munin-update 2.0.25),
2583 a 2651 je asterisk 13.4.0 a nakonec 2828 je apache-2.4.16

Zajimave na tom je ze procesy po nejakem case se ze stavu Z zotavi.
Strace mi na to nefunguje:

strace: attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted

Pravdepodobne omezeni OpenVZ??? Ta nemoznost debugovani je docela
zvlastni a uvnitr OpenVZ kontejneru nevim co s tim, pristup k
/proc/sys/kernel/yama/ptrace_scope nemam, takze jediny vysvetleni ktery
mne napada je chyba/omezeni OpenVZ a nebo ze uz tenproces nekdo debuguje
(gdb/strace).
