Using the auth_pam module to implement HTTP AUTH:
Once in a while authentication seems to stop working across all browsers
and users. The error that shows in the Nginx error log file when a
tries to authenticate is:
Can’t initialize threads: error 11
(Verbatim, the error has no timestamp or anything else)
Restarting Nginx fixes the problem for some time (days?).
Next time I’ll try a reload instead.
Searching for that error doesn’t turn up too much, except that it
might be a MySQL error(?)
Can anyone help? Is the author Sergio on this list?
