Hola tengo el siguiente inconveniente:

Tengo un servidor HP con asterisk el cual a veces se queda congelado y lo tengo que reiniciar.

En el /var/log/messages aparece el siguiente error:

Alguien me puede ayudar con este problema? :smiley:

Gracias.

Tu problema podria ser un problema de memoria ram, pero en todo caso te recomiendo que busques errores especificos en los logs de asterisk y los analizes atentamente hay esta la respuesta a cualquir problema

te recomiendo usar cualquier de estos comandos y luego leer detenidamente lo que te salga en pantalla.

grep -i error /var/log/asterisk/messages | less

root@Asterisk-PBX:~# cat /var/log/asterisk/messages | grep -i error | less

root@Asterisk-PBX:~# cat /var/log/asterisk/messages | grep -i warning | less

grep -i error /var/log/asterisk/messages > error.txt

This is a hardware or kernel problem NOT an Asterisk one. There is a small chance that it could be dahdi related but all the blocked system calls seem to be file system related.

There is a possibility that some PCI telephony hardware is conflicting with a mass storage controller.

Settle down, gents.
