While installing on my shared host, it became clear that either their chron does not pass args, or chronzweather is referencing them incorrectly. Neither argv[0] nor argv[1] displays any value in the usage error message issued.

I removed the check and the argc loop, and hard-coded the url, and it worked.

However, it then issued a "not authorized" message and advised me to add the IP address in the globals. I did this, and now its working OK.

Version 6b2, downloaded 24-apr-09.

I have uninstalled z-weather due to a large number of errors, such as the following.

"**** Error: Bad Alert XML file (parseXML)" and

"DB function failed with error number 2006 MySQL server has gone away SQL=SELECT *
FROM jos_modules AS m
WHERE module = 'mod_zweather' and published = 1
ORDER BY m.id ASC"

delivered by e-mail,

and these, in the php-errorlog file, repeating hundreds of times, but apparently not every execution:

My php_errorlog was 528k when I disabled the chron job.

Hi Pat,

Sorry to hear of the problems, which I think are interesting since all the messages you are listing are coming from the Joomla application. You should check the version of your libXML library (from admin, help->system info->php information) to make sure you are not experiencing a known issue with that library.

Thanks -- you may be right. I checked and the version of libXML is very old, 2.6.23 from January, 2006. I have no real way to deal with this. I've never contacted the web-host people. (I think there's a charge to do so.) After uninstalling z-weather, the errors are still occurring, but very infrequently -- 8 to 10 in the last day or so. With z-weather's chron job running it was hundreds, perhaps, per hour.

I've never noticed any unexplained odd behavior on the site.

Actually, you are OK with the libxml version. A bug was introduced in versions 2.7.1 and 2.7.2, so actually, you are better off with the older version! What version of Joomla and php are you using?

Joomla is 1.0.15 Stable [ Daytime ] 22 February 2008 23:00 UTC
