[erlang-questions] disk_log question

[Bengt Kleberg]

Greetings,

>From the documentation (http://erlang.org/doc/man/disk_log.html):

"A process that opens a disk log can either be an owner or an anonymous
user of the disk log. Each owner is linked to the disk log process, and
the disk log is closed by the owner should the owner terminate."

If you open as an owner and if your shell crashes when the module
returns an error (badmatch?) the log will be closed.
Could this be what is happening?
