| |
Hello,
I've been chasing an OOM-death problem on 2.6.17 that showed up while running a J2EE application on my recently-built Gentoo box. The crash was ugly - leaking huge numbers of skbuff_head_cache and size-2048 slab entries until my java processes died and the system became unusable and unresponsive.
My environment is:
Gentoo kernel build 2.6.17-gentoo-r8, built with GCC 4.1.1.
I tried Catalin Marinas' kmemleak patches, and had to rebuild with GCC 3.4.6 because of a 4.1.1 compiler bug that prevents compilation of the patches.
And... building with 3.4.5 fixed the leak! So I guess I have very little detail to report - except that there's a nasty leak in 2.6.17 when built with 4.1.1.
If anyone has a version of kmemleak that I can build with 4.1.1, or any other suggestions for instrumentation, I'd be happy to gather more data - the problem is very easy for me to reproduce.
