Dear Fengguang, > There are 260MB reclaimable slab pages in the normal zone ...
Marked "all_unreclaimable? yes": is that wrong? Question asked also in: http://marc.info/?l=linux-mm&m=135873981326767&w=2 > ... however we somehow failed to reclaim them. ... I made a patch that would do a drop_caches at that point, please see: http://bugs.debian.org/695182 http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=101;filename=drop_caches.patch;att=1;bug=695182 http://marc.info/?l=linux-mm&m=135785511125549&w=2 and that successfully avoided OOM when writing files. But, the drop_caches patch did not protect against the "sleep test". > ... What's your filesystem and the content of /proc/slabinfo? Filesystem is EXT3.
