Has these 4.0 bugs been fixed yet ? I saw them in the June 1989 Customer
Distributed Buglist.
==========================================
Reference #: 1011562
Release: 4.0
Synopsis: writes to some files can get lost
Description:
An nfs server can lose a write to a file if the file is written on a 4.0
SunOS server while being accessed for an fns read request in some
circumstances. The data written will be part of the file for a while. But
later if the data has to reread from disk, the same file will have old or
garbage data.
Reference #: 1014577
Release: 4.0
Synopsis: NFS mounted files occasionally get garbage/nulls written to them
Description:
Occasionally when writing to nfs mounted files, parts of a file are replaced
exactly (no insertion or deletions) with garbage, usually nulls. This can
span several appends to the file by distinct processes running minutes
apart.
Reference #: 1009122
Release: 4.0beta
Synopsis: Sometimes read operations fail
Description:
Mysterius I/O errors appear with SunOS 4.0. The symptom varies but it seems
as if reads from disk files sometimes return bogus data.
==========================================
These are really serious bugs especially when one has an nfs server acting
also as a centralized mailserver (bug 1011562) and /var/spool/mail is
centralized on the mailserver and hence nfs-mounted by other clients (bug
1014577) -- I'm getting bogus data & old mail messages got overwritten in
people's system mailboxes from time to time. My whole net is running OS
4.0.1 (I've both Sun-3 & Sun-4 architecture nodes/servers).
Any pointers would be greatly appreciated.
