Ca prima faza da-i un yum update, 6.9 e lansat oficial (iar la mine merge OK pe toate serverele de 10 zile). Citeste intii insa release notes de la RHEL, sa fii sigura ca nu ai surprize de la chestii deja documentate.
Cum probabil nu o sa aiba efectul scontat, vezi ce zice si serverul Windows in timp ce linuxul e agatat... si monitorizeaza si traficul prin retea. Mie imi miroase a problema provenind de la "altceva", kernelul linux ramine agatat asteptind ceva dinspre serverul Win.
