Hello, I confirm this bug. All processes are being logged with UID 0. sa -m gives me correct output about time, but wrong about user usage, because all the time goes to account root and no other users are reported Tested with the following kernel versions: 126.96.36.199 188.8.131.52 2.6.32 Working correctly with: 184.108.40.206 I tried various configs, but no luck so far. OS: CentOS 5.4 Linux centos5-64 2.6.32 #1 SMP Mon Dec 14 11:24:29 EET 2009 x86_64 x86_64 x86_64 GNU/Linux Gnu C 4.1.2 Gnu make 3.81 binutils 220.127.116.11.6 and 2.20 tested too util-linux 2.13-pre7 mount 2.13-pre7 module-init-tools 3.3-pre2 e2fsprogs 1.39 Linux C Library 2.5 Dynamic linker (ldd) 2.5 Procps 3.2.7 Net-tools 1.60 Kbd 1.12 Sh-utils 5.97 udev 095 enabling/disabling CONFIG_BSD_PROCESS_ACCT_V3 makes no difference tested with GNU Accounting Utilities (release 6.3.5-ts02-12) GNU Accounting Utilities (release 6.5.1), The .config file is attached to this bug.

Hello again, I tracked down when the problem first appeared. The problem comes with this commit: http://git.kernel.org/?p=linux/kernel/git/next/linux-next.git;a=commitdiff;h=d8e180dcd5bbbab9cd3ff2e779efcf70692ef541 My temporary resolution is reverting the patch between, but I guess it is better a kernel developer to take a look at it. linux-18.104.22.168/kernel/acct.c and linux-22.214.171.124/kernel/acct.c
