7800X web gui crash and then routing fails

Hi,
I've just bought a 7800X and so far I'm not very impressed!
After approx 2-3 hours uptime trying to change settings via the web gui causes the unit to fail to respond to http or telnet access and WAN ping doesn't respond. Internet routing and LAN ping is OK for a further period but then fails also.
A power cycle cures.
Similar reports here:

and here:
viewtopic.php?f=18&t=2185
The unit was supplied running 2.32b and I set up many static DNS entries before using online. I upgraded to 2.32c, restored factory settings, and then merged in the DNS reservation section of xml to save much typing.
Config posted on eSupport with password set to 'admin'
Is there a bug with 2.32c and is it worth going back to 2.32b (if I can find it?)
Thanks

More information. I rebooted the router at 10AM (after a crash of the GUI at 0930) and didn't try to do anything with the web GUI until 3PM. At this point I set up a single Virtual Server rule and when I clicked on apply the web gui didn't respond and failed to load the page. As browsing was still OK and I left the unit for further 15mins before rebooting. During this time, I monitored a Thinkbroadband broadband quality graph and you can see that the latency shot up. This occurs on other occasions where the web GUI locks up.

Running a syslog server I found this:

Something clearly amiss!

Crashed again overnight (2AM), this time not provoked by accessing the web GUI or any user activity. Router LAN responding to pings but http, telnet, ssh and dhcp servers not responding and routing had failed.

Further update: I re-flashed to 2.32b and continued to configure my settings (a lot of static DHCP reservations and about 10 time restrictions) and the router then crashed. An attempt to restart it apparently failed but the syslog dump showed it was crashing when the WAN came up. Rebooting with the WAN disconnected brought back life but the unit crashed again when it was plugged in.
As a final test I reset the router to factory default and flashed 2.32c again. Then I loaded the big config I'd been using with 2.32b and the unit crashed immediately (without the WAN connected) Only a pin-hole reset brought it back to life and I've now configured it with the bare minimum changes and it seems to be OK.
My conclusion is there's either a memory fault with my router or there's something fundamentally wrong with the firmware and it's ability to handle config files of around 25k or more. I've added the configs to the ticket in e-support but it would be useful if someone with a 7800X, or indeed any of this series of models, can reproduce the problem (add in some time restrictions and add in around 30 DHCP reservations, backup the config file and make a note of its size).
If it is reproducible hopefully Billion will fix it quickly but if I haven't heard from Billion UK before the end of the week I suspect my use of the brand will be short lived

Best bet is to stay on firmware 2.32c as this is the latest, I have forwarded your config/logs over to our engineers to comment on, I will update you via our esupport
I have never seen this issue on the 7800DXL/VDOX/DX, so some further investigation will be needed

Good morning
I am bipac 7800X for a couple of days and i have installed the firmware etec7800_2.32c and after this, i have the same problem (7800x crash after 4 or 5 hours). I have change the firmware etec7800x_2.32c and install the Australian firmware PCRange7800x_2.32c and now, it seem that bipac don't crash. I think that Bipac buy in England is a Australian router. What do you think about this ? Thanks. Notargia

I have reported this issue to our engineers, I don't think there is that many major changes between our firmware and AU firmware (but I can't comment much as we don't work on the AU firmware only UK firmware)

To add to my feedback - I'm now running with a minimal config and having to set the router to reboot every night at 1AM as it crashed after around 2-3 days uptime.
Looking for confirmation that the fault is reproducible (the ticket reply suggests it is) and a timescale for a fix...

Just chased our engineers waiting for a reply now, I will drop you a reply via our esupport ticket system
