RHEL AS3 - Trying to mount CD get "mount: Cannot allocate memory" error

[Stuart Allan]

Hi,

When trying to mount an Oracle client CD in some RHEL AS3 servers using:

# /bin/mount -t iso9660 -r /dev/cdrom /mnt/cdrom

I'm getting the following error message:
"mount: Cannot allocate memory"

I had this issue on four Redhat servers and have since rebooted two of them and now can mount CDs ok in them, but the other two are production servers and rebooting is not a desirable option or long-term fix for this.

I'm thinking this is some sort of memory leak maybe requiring a patch but can't find anything specifically related to this.

Specs for one of the servers:

HP Proliant DL580, 2 Xeon CPU 2.20GHz, 4GB RAM
Red Hat Enterprise Linux AS release 3 (Taroon Update 8)

Try using this syntax:

/bin/mount -t iso9660 -r /dev/cdrom /mnt/cdrom -o loop

Thanks, but I still get the same message with this syntax:

# /bin/mount -t iso9660 -r /dev/cdrom /mnt/cdrom -o loop

/dev/cdrom: Cannot allocate memory
