Hi Andrew,
Here is the output with the symbols inserted. I can reproduce this
memory leak very reliable now, by just activating the vis server
(didn't do that with the logs I've posted before) in a couple of
minutes. free is showing a nice countdown then :).
For kmemleak... I'm using 2.6.30.10 here and I think Torvalds
merged it into 2.6.33 a month ago. Anyone having a 2.6.33 kernel
running at the moment, patches for kmemleak in 2.6.30 or another
idea of how to debug this in 2.6.30?
"Debug slab memory allocations" (CONFIG_DEBUG_SLAB) and "Memory
leak debugging" (DEBUG_SLAB_LEAK) are activated on the kernel I'm
using here, but they are not of any use, are they?
Cheers, Linus
