qmail a pomale dorucovani

[Milan Roubal]

DD,
mam problem s qmailem. Pred poslednim restartem pocitace chodilo vse bez problemu, ale
od posledniho restartu se zacaly zpravy dorucovat neuveritelne pomalu.
Bohuzel nevim co vse se za ten cas mohlo zmenit v konfiguraci, predchozi uptime byl kolem 100 dni.
Situace vypada tak, ze vsechny zpravy ktere prijdou se v poradku doruci, log vypada takto:
cat /var/log/mail:

Jak vidite je tu spousta akci ktere byly spustene jakoby podle logu v jeden okamzik,
pricemz ty maily byly posilany v jiny cas, akorat tenhle cas doruceni je stejny.. Jako kdyby
qmail cekal na vice zprav a ty pak dorucil naraz. Bloky maji ruznou delku, od 1 do 8 zprav dorucenych najednou.
Interval nema zadnou logiku, proste najednou se jakoby vzpamatuje a vse se doruci do maildiru.

vypis procesu vypada takto:
nica:/service # ps ax | grep -e "qmail"
26324 ?        S      0:02 qmail-send

kernel je 2.4.17
co tohle chovani muze zpusobovat a jak postupovat pri hledani problemu? Prosel jsem si vsechny konfiguraky a zdaji se byt v poradku.
Zdravi
