Description Sam Varshavchik 2001-09-10 02:25:42 UTC

Description of Problem:

In RC1, "rpm --setperms dev" starts eating CPU time in an infinite loop. 
This is also true for released 7.1 (rpm-4.0.2-8, dev-3.1.0-14).

Version-Release number of selected component (if applicable):

dev-3.2-3
rpm-4.0.3-0.93

Comment 1 Chris Ricker 2001-09-10 02:36:36 UTC

Hangs on RC2 as well, looping on one of the CPUs

here's the last snippit of the strace:

mmap2(NULL, 745472, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x40238000
open("/etc/mtab", O_RDONLY)             = 5
fstat64(5, {st_mode=S_IFREG|0644, st_size=488, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x40014000
read(5, "/dev/hde6 / ext3 rw 0 0\nnone /pr"..., 4096) = 488
close(5)                                = 0
munmap(0x40014000, 4096)                = 0

read(5, "        total:    used:    free:"..., 4096) = 603
close(5)                                = 0
munmap(0x40014000, 4096)                = 0

brk(0x8064000)                          = 0x8064000
brk(0x8072000)                          = 0x8072000

Comment 2 James Manning 2001-09-10 03:08:40 UTC

It's not an infinite loop, it's actually making progress, it just takes awhile:

On my P3/800:

[root@jmm root]# time rpm --setperms dev
real    5m52.197s
user    5m2.840s
sys     0m25.420s

OK, thanks for verifying, closing NOTABUG.
