Recently I installed print server CUPS http://www.cups.org/ , followed this howto: http://blog.jameslick.com/?p=867 . I followed http://wiki.openwrt.org/PrinterSharingHowto and http://wiki.openwrt.org/UsbStorageHowto .
USB stick is spool for CUPS. With fdisk I deleted partition and created new one, formated to ext3 and mounted as ext3 to /mnt.

The problem is since then router from time to time stop printing. I can login to router, I can connect to openVPN installed on router, but I can't login to CUPS console. Even more router don't respond to 'reboot'. The only way is to plug out and in router. After that everything is ok until next 'crash'.

I have no idea where to start from that. Where should I look and what is the problem.

Hi,
could you please post your cupsd.conf?
It should look like that.
RequestRoot /spooler
TempDir /spooler
(/spooler is your usbstick)

With "I cannot access the Cupsconsole" you mean the Cupswebside? (routerip:631)

For me it looks like the router is running out of free spacec (if it is connected to cups) or some other error which is not related to cups in any way but to usbload or something like that.

with best reagrds

yes.

I'll look for it. 256MB USB stick is plugged in so I think it is enough space for spool.

Hi,
how much jobs does your router have to manage at the same time?
I'm using a Wl-500gx and havent had any probs yet so I do not think it is CPU-load which causes this.
(the gx has a weaker CPU and less Ram than the gP)
But I'm using a 1Gb usb-stick. I read on this forum that one job can use more than 200mb while spooling.
Can you see if your usbstick is active during printing? Maybe it has a LED indicating traffic?

with best regards

max 2

I've checked and while crash CPU-load is max 20%

Most of the documents have 1 or 2 pages so it should not be a problem.

No I can't see it because its remote router.

Since morning route has crashed 2 times. In the 2nd time I have logged in and dmesg showed in this lines:

I looked to /mnt/usb (where I mount partitnion from USB stick) and it was empty! There should be 2 directories. df showed that mounted partition like everything was ok.

Any ideas what to do?
