glibc problem

[Jan Polak]

Zdravim vsechny.

Problem:

Systemy: rh 7.1 a rh 7.2 vcetne vsech upgrade...
Po upgade na glibc 2.2.4-30 vypadalo vse OK, az do restartu MySQL
(zkouseno na nekolika strojich s bezicim named i bez nej)

mysql pripojeni pres sock jsou OK, ale na tcp spojeni mysql pada (viz nize 
cast vypisu strace)
Pokud se mysql spusti s --skip-name-resolve, tak jede bez problemu jak na 
socketu tak na tcp 3306

Podobne se chova i lotus domino - smtp proces pri navazani spojeni ven 
sestreli cele domino
(opet vyzkouseno na nekolika strojich).

Po downgrade na glibc 2.2.4-29 se mysql i domino chovaji normalne.

nejake napady?
