Hi Gustaf,

The crashes we are seeing are not during shutdown, but during normal server
operation which is why we are concerned about them. The system recovers
quickly due to daemontools, but the scheduled tasks running at the time of
the crash are aborted.

There is nothing in the syslog to indicate a memory problem or oom killer
being invoked.

As for a Tcl bug, we might potentially be able to upgrade the version of
Tcl use to 8.5.17 from the Debian testing distribution (currently we use
8.5.11). But I wouldn't like to do that on the production system unless
there was very good reason.

Do you know more about the Tcl bug that caused your last crash?
