Several memory leaks were fixed in the U1 kernel. Please try and reproduce on 2.6.9-11.EL I will try this kernel. Thanks! Closing bug, Issue 76923 has been opened to mirror the IBM bug I used a simpler script as follows to reproduce this problem,so I will reopen it. Environment: RHLE4 U3-BETA(2.6.9-22.EL) IBM Power4 ------------------------------------------------ export LTPROOT=/root/ltp-full-20050307 export PATH=$PATH:${LTPROOT}/testcases/bin cd ${LTPROOT} mkdir -p /test/aiodio/junkdir while : do ${LTPROOT}/testcases/kernel/io/ltp-aiodio/fsx-linux -N 10000 -o 32768 - l 500000 -r 2048 -t 2048 -w 2048 -Z -R -W /test/aiodio/junkfile done ------------------------------------------------ There is one thing I noticed that the problem will not occure if run fsx-linux without '-Z' option(O_DIRECT). Correct myself,the kernel version should be 2.6.9-24.EL,RHLE4 U3-BETA Created attachment 122121 [details]

I record the usage of mem and swap in the whole test.
