Kernel bug (cosa fare?)

[Massimo Rossi]

Buongiorno a tutti,
abbiamo in housing un server Dell 2850 ed è la seconda volta che freeza 
in breve tempo.
Ha su RHEL4 con kernel originale non ricompilato, ecco alcune info:

Pare faccia riferimento a java.bin, ma non ho trovato niente negli altri 
log file.
Vorrei cercare di capire da cosa deriva e pensevo di inviare una mail a 
chi si occupa del kernel.
Secondo voi è la strada giusta ed esiste una procedura da seguire?

Grazie
