The LWN archive server is running Debian's 1.9.0 public-inbox package.
Every now and then, usually after at least a week of operation, HTTP
requests will start returning empty messages; I find stuff like this in
the log:

Nov 05 15:24:37 archive2.lwn.net public-inbox-httpd[1267166]: Use of uninitialized value in index at /usr/share/perl5/PublicInbox/Eml.pm line 109.

The pattern is pretty much always the same.  Restarting
public-inbox-httpd makes the problem go away again.

Is this a problem that anybody else has seen, or am I especially
lucky...?

Thanks,
