3 LIST OF KNOWN BUGS IN AM-UTILS OR OPERATING SYSTEMS

6(1) mips-sgi-irix*
7
8[1A] known to have flakey NFS V.3 and TCP. Amd tends to hang or spin
9infinitely after a few hours or days of use. Users must install recommended
10patches from vendor. Patches help, but not all the time. Otherwise avoid
11using NFS V.3 and TCP on these systems, by setting
12
13 /defaults opts:=vers=2,proto=udp
14
15[1B] yp_all() leaks a file descriptor. Eventually amd runs out of file
16descriptors and hangs. Am-utils circumvents this by using its own version
17of yp_all which uses udp and iterats over NIS maps. The latter isn't as
18reliable as yp_all() which uses TCP, but it is better than hanging.

23hasmntopt(mnt, opt) can goes into an infinite loop if opt is any substring
24of mnt->mnt_opts. Redhat 5.0 does not have this libc bug. Here is an
25example program:

27#include <stdio.h>
28#include <mntent.h>
29main()
30{
31 struct mntent mnt;
32 char *cp;
33 mnt.mnt_opts = "intr,rw,port=1023,timeo=8,foo=br,retrans=110,indirect,map=/usr/local/AMD/etc/amd.proj,boo";

78There's a UDP file descriptor leak in libnsl in RedHat Linux 5.1. This
79library part of glibc2. Am-utils currently declares redhat 5.1 systems as
80having a "broken yp_all" and using an internal, slower, leak-free version.
81The leak is known to the glibc maintainers and a fix from them is due soon,
82but it is not yet in the glibc-2.0.7-19 RPM.

87A bug in libc results in an amq binary that doesn't work; amq -v dumps core
88in xdr_string. There is no known fix (source code or vendor patch) at this
89time. (Please let amd-dev know if you know of a fix.)
