- Hello,
-
- some users here use the Perl program 'aub' (assemble usenet binaries),
- Author stantz@sgi.com, to process image files received via USENET.
- Somehow this program seems to manage to corrupt the open file table in the
- user area so that ULTRIX crashes e.g. when the program is exiting and the
- files are being closed. It apparently leaves a large number of files
- behind, because fsck on /tmp, where this program was supposed to create
- files, complains about unconnected files and other strange anomalies. It
- looks as if the program is going beyond 64 open files before the crash
- occurs.
-
- Has anyone seen a similar behaviour? Any ideas for a fix?
-
- Some configuration details: DECserver 5900, Prestoserve, ULTRIX 4.2A,
- Perl 4.035, aub v2.0 and v2.0.5 behaving alike.
-
- Panics that we have seen sofar:
- gfs_lock: locking unrefed gnode
- km_free: bad addr
- unaligned access
-
- Any help would be very much appreciated.
