App in crash su OS X Server 10.6 con errore di segmentazione

Sto riscontrando uno strano problema su un server Web che esegue OS X Server 10.6.8. Qualsiasi app che provo ad aprire finisce per bloccarsi immediatamente con un errore di segmentazione. Questo vale per le app gui come Safari o Calculator, ma anche per strumenti a riga di comando come xcodebuild. Le app attualmente in esecuzione sembrano continuare a funzionare, ma non è possibile avviare nuove app.

$ xcodebuild -version
Segmentation fault

Ecco il registro degli arresti anomali per xcodebuild:

Ecco un registro degli arresti anomali da Calculator.app. Come si può vedere, che portarono molte somiglianze ( _SCUniverseGetEntryAddress, FileIDTree_FindVolumeRecordFromDeviceID, ecc).

Quindi, cosa dà? Sono tentato di riavviare, ma con un problema così grave temo che il sistema operativo potrebbe non tornare affatto.

Abbiamo riscontrato esattamente gli stessi sintomi su 10.6 (non è possibile avviare nuovi processi e i loro registri indicano che si sono arrestati in modo anomalo su _SCUniverseGetEntryAddress) in diverse occasioni. Ho avviato il computer dal disco di sistema e riparato l'unità di avvio e sembra funzionare finora. Un'altra persona ha descritto qui che la disattivazione delle anteprime per le sue registrazioni EyeTV ha risolto i suoi problemi.
