Hi, I noticed that my system's (kernel 2.4.22) cache memory is fast reducing. Its normal value is around 225M always. its reduced to 175M over about 30 days and still going low. I notice this unusual behaviour /proc/slabinfo. total size-32 objects are very large. about 300 objects of some type are being added to size-32 slab every 10min. There is no sign of any reduction. size-32(DMA) 0 0 32 0 0 1 size-32 1979925 1979986 32 17522 17522 1) What kind of driver/kernel functions need to allocate such size-32 objects. ( for eg, if inode is for file inodes, size-32 is for ???) 2) Would it be possible to view the objects (any tool/utility for this) 3) What does this uncontrolled growth imply? is someone requesting size-32 objects uncontrollably or the Virtual Mem/slab is failing to release the cache. or could it be both ? 3) If this is some driver's fault, what kind of flags/code do i grep in driver dir, so that it will help me figure a faulty driver (eg; SLAB_NO_REAP ?) Thanks in advance.
