You can do cat /proc/meminfo | grep Slab and if that grows too much over time you can do cat /proc/slabinfo or use a tool such as slabtop to see where the memory is going. If the memory is being leaked in the kmalloc caches, you can use CONFIG_DEBUG_SLAB_LEAK which part of the kernel is doing all those allocations (not really suitable for production machines). Also remember to check that Active + Inactive + Buffers + Cached is roughly the same size as MemTotal - MemFree; otherwise your kernel might be leaking full pages. Christoph, I suppose there's some option to Documentation/vm/slabinfo.c that provides similar output to CONFIG_DEBUG_SLAB_LEAK for SLUB?

For slub: Just enable debugging and then do a cat on /sys/kernel/slab/<cachename>/allocs or frees to see where memory is allocated or freed. > Christoph, I suppose there's some option to > Documentation/vm/slabinfo.c that provides similar output to > CONFIG_DEBUG_SLAB_LEAK for SLUB? If you run a report on a slabcache with f.e. slabinfo kmalloc-2048 and debugging is enabled then all functions that allocate and free objects in kmalloc-2048 are listed. Just doing slabinfo list all caches with the number of objects allocated. ^ permalink raw reply [flat|nested] 11+ messages in thread

Not sure what this is about. per cpu cached objects? slabinfo -s will shrink all caches and throw all cpu slabs away. The system will touch some essential caches immediately though. So some processor will immediately reallocate cpu slabs. ^ permalink raw reply [flat|nested] 11+ messages in thread

However, after some analyzes and enabling DEBUG mem features of the kernel , I found anormal proc_inode_cache , and a bug in fork process (my kernel has got patches enabling Realtime features) This has been corrected, but know, I am waiting again for new results of stability , there may be other problems.

Compile the slabinfo tool. gcc -o slabinfo linux/Documentation/vm/slabinfo.c Then you can do slabinfo -T to get an overview of how much is used by slabs. But I do not see that slabs are using an excessive amount. So toying around with slabinfo is not going to get you anywhere. ^ permalink raw reply [flat|nested] 11+ messages in thread

Do you think I have to switch to SLUB ? 2) regarding memory debugging, your reply and some mesages told it was normal the memory was growing (with ext3 buffer_heads...) and released on demand. This sounds to me it becomes VERY VERY difficult telling if my system is STABLE or NOT. Is there a way to bypass it ? I assume I have to do some kind of small program trying to allocate almost the full remaining memory available at startup to empty caches ?

Is there a way to bypass it ? This the basic design of memory handling in Linux. Why would the use of memory mean that your system is unstable? > I assume I have to do some kind of small program trying to allocate almost the > full remaining memory available at startup to empty caches ? There is a way to drop caches. See what you can do with /proc/sys/vm/drop_caches f.e. echo 1 >/proc/sys/vm/drop_caches echo 2 >/proc/sys/vm/drop_caches Should free most of memory. ^ permalink raw reply [flat|nested] 11+ messages in thread
