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.
