/me has a flash of inspiration.... cron starts all the jobs approximately simultaneously, calling through pam to start sessions for each..... for each job, pam_ecryptfs.so increments the refcount file in /tmp/ - and the various invocations of pam_ecryptfs.so race with each other, in a textbook classic "lost updates" race condition.
When the jobs terminate, they've usually spread out enough in time that you are less likely to get the same loss of counter decrements. Hence, more decrements than increments actually take effect, and the refcount hits zero. -- ecryptfs private directory randomly unmounts https://bugs.launchpad.net/bugs/358573 You received this bug notification because you are a member of eCryptfs, which is subscribed to ecryptfs-utils in ubuntu. Status in eCryptfs - Enterprise Cryptographic Filesystem: Confirmed Status in “ecryptfs-utils” package in Ubuntu: Confirmed Bug description: Binary package hint: ecryptfs-utils This seems to be bug #259293, but I am filing a new one as I haven't seen this in some time. Twice in the last week my ~/Private directory unmounted. Both times /tmp/ecryptfs-<user>-Private was '0'. Both times, the symlink in the unmounted ~/Private was not present. I have a cron job that runs every 10 minutes that I can see in syslog: Apr 9 11:15:04 hostname CRON[22771]: Mount of private directory return code [0] It could be that bug #259293 is simply 'mostly' fixed and I coincidentally hit this twice in the last week, or it could be a new bug (I don't know).
