ModPerl and Net::Z3950

[Ian Stuart <Ia...@ed.ac.uk>]

We are using Apache/1.3.26 (on a Sun Solaris box), with mod_perl/1.27,
in an ASP/Event-driven service that does Z39:50 database queries to get
the data.

We have been getting errors saying that the connection dies, causing
Net/Z3950/Manager.pm to die.

This problem occurs randomly, and we cannot work out if it is
time-the-servers-been-up-based or number-of-connections-to-date-based.
We *do* know that the problem is cleared if we do a graceful restart of
the apache server.

So:
1) Has anyone successfully used Net/Z3950 in a mod_perl environment?
2) Has anyone tried, met a similar (and unresolvable?) problem?
3) Has anyone had a similar problem, and solved it a different way?

In anticipation...

I rather doubt that... :)

No, no and almost everybody in that order :).  Have you tried
adjusting the value of MaxRequestsPerChild to see if it helps?
