Description Shawn 2003-05-14 02:39:54 UTC 
Description of problem:
When rpm is run on redhat 9.0 on linux-2.5.x as root, it hangs, and select()
times out. The problem is related to O_DIRECT, apparently. Here's output from
the command:
  [root@www root]# rpm -qi iptables
  rpmdb: unable to join the environment
  error: db4 error(11) from dbenv->open: Resource temporarily unavailable
  error: cannot open Packages index using db3 - Resource temporarily unavailable
(11)
  error: cannot open Packages database in /var/lib/rpm
  package iptables is not installed
  [root@www root]#

Version-Release number of selected component (if applicable):
  db4-devel-4.0.14-20
  db4-4.0.14-20
  rpm-build-4.2-0.69
  db4-utils-4.0.14-20
  rpm-devel-4.2-0.69
  rpm-4.2-0.69

How reproducible:
use rpm as root under linux-2.5.x on redhat 9.0

Comment 3 Shawn 2003-05-14 02:45:28 UTC 
Oh, forgot to mention... The following command allows execution of rpm as root,
as it makes it ignore O_DIRECT..
  LD_ASSUME_KERNEL=2.2.5 rpm -qi yadda yadda

I got this info from akpm in lkml, so if you want to search the archives for the
thread, search for the subject "Re: odd db4 error with 2.5.69-mm4 [was Re:
Huraaa for 2.5]"

Thanks dudes...

The following bugs might be clueful:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=86381
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=88178

By the way, what would make 2.5.69-mm4 not NPTL savvy?
Comment 5 Jeff Johnson 2003-05-14 15:12:21 UTC 
Yup. O_DIRECT use by db-4.1.25 is hacked out in (at least)
rpm-4.2-1 (just released), but it's gonna be a mess.
