>Number: 3267 >Category: kern >Synopsis: mtime/ctime sometimes updated when a program is run >Confidential: no >Severity: critical >Priority: high >Responsible: freebsd-bugs >State: open >Class: sw-bug >Submitter-Id: current-users >Arrival-Date: Sat Apr 12 11:30:01 PDT 1997 >Last-Modified: >Originator: Kevin Martin >Organization: pair Networks >Release: FreeBSD 2.2.1-RELEASE i386 >Environment: Fresh 2.2.1-RELEASE installation, no active users, only cron jobs. >Description: Cron jobs, which run every ten minutes, make several calls to /usr/bin/grep and /usr/bin/wc - once or twice per day, these files get their ctime and mtime updated to the current time. This has also been seen in the past with 2.2-BETA_A and 2.2-GAMMA. It has been reported as early as February 1996 for FreeBSD 2.0.5. The most serious concern is that when this problem was occuring on a heavily loaded 2.2-BETA_A system, we also saw numerous filesystem corruptions (disappearing files, etc) - although there is no proof that this is related. >How-To-Repeat: Have been unable to repeat by running programs manually many times, but it happens routinely if not consistently when run from a cron job (as root). See also the archives of freebsd-bugs and freebsd-questions, when searched for "mtime and ctime". >Fix: Unknown. Errant filesystem bug? >Audit-Trail: >Unformatted:
