Hi. I'm experiencing a problem with 2.6.15.4 / 2.6.16-rc4, noticed during high disk IO (copying a lot of data between 2 machines): the system memory get filled up, until the full swap is used and the system must be rebooted (or is unusable). Stopping the process does not free the memory, and happens not only copying via network, but also with a simple cp -a dirwithmanybigfiles testdir. The system is running on athlon64: Linux morgor 2.6.16-rc4 #2 SMP Sat Feb 25 19:55:36 CET 2006 x86_64 x86_64 x86_64 GNU/Linux Same issue with 2.6.15.4 The box has a single soft-raid1 device made by 2 sata disk on promise controller. Attached slabinfo dump and dmesg dump.
