Is this perhaps a swap/memory full problem? I have it running on a flash stick (but setup in turnup with turnup disk -i)... two partitions, one root, one swap. just watching top as I restart the wview daemons... things run fine until htmlgend starts up... it takes up 4% then 5 then 7% of memory, and then it reports 35% of memory... and/or crashes. i will try turning off a bunch of my images see if that helps Back to top bhnb Joined: 28 Nov 2005 Posts: 127 Posted: Thu Jul 06, 2006 11:48 pm    Post subject: I suspect this is down to a compatibility problem with the files copied from your old setup. IIRC that was a Mac, also big-endian so this shouldn't be an issue. If your files *are* litlle-endian, you'd need to run them through arc-le2be. On the subject of swap, I've never seen usage above about 24MB on my heavily-loaded production slug. For a standard wview install it probably only swaps when you run ipkg update. So some swap is essential, but the behaviour you're seeing almost certainly won't happen once the file problem is sorted. And if you're running on a flash stick but using turnup disk, I'd recommend passing it 'noatimes' to reduce some of the wear.

I'll run them through the converter and see what happens. i was surprised by the swap usage as well, it would make sense if it was the big/little endian issue fouling that up too.... i'll check it out. did you use the turnup memstick option instead? I tried that, but ran into some errors relating to turnup setting up the /var/log in flash instead of on the memstick. So i eliminated the problem by going to disk mode. Yep, I've added the noatime option to hopefully keep the wear down thanks for you help. chris Back to top chrisale Joined: 09 Nov 2005 Posts: 187 Posted: Fri Jul 07, 2006 9:42 am    Post subject: looks like the archive big/little endian issue was it... everything seems to be fine now. I unfortunately cleared the data logger on the VP unneccessarily last night... so I've lost a couple days of data... but better than 6 months! thanks for you help John!

If I was running wview on a memstick I'd do turnup disk as well - I've run a wview simulator this way.
