Package: perl
Version: 5.8.8-7
Severity: important
(marked as important due to data corrumption when reading a file)
I have a process that reads a file, line by line with <FILE>, while
another process is creating it. The normal behavior is to get a
truncated file. A problem occurred when a line
[F7133666,00000042] [4145231462,66]
was read. Instead of getting this line (possibly truncated), I got
^...@^@^...@[...]^@^...@^@ [4145231462,66]
with 2463 null characters. The tab character is at position 0x85000
in the file. The file is acceded via NFS (on two different machines).
However, without any concurrent writes, one shouldn't get such null
characters.
I don't know if the bug is in Perl (perhaps a buffering bug), glibc
or in the kernel...

Ok, thanks for the answer. Closed.
