PHP Fatal error: Uncaught ValueError #35

Closed kitenski closed 1 year ago

kitenski commented 1 year ago

I noticed my long running 123solar wasn't up, everytime I restarted it, it died quickly.

Turning on debug shows the following:

* 31/10/2022 12:03:08 Starting 123Solar debug (1461)

PHP Fatal error: Uncaught ValueError: fread(): Argument #2 ($length) must be greater than 0 in /srv/http/123solar/scripts/123solar.php:650 Stack trace:

weird you have so many ones.. It's when it does the "Riso" test If it happen again report with which protocol file you use.

kitenski commented 1 year ago

UK autumn at it's finest, or old panels maybe?

jeanmarc77 commented 1 year ago

A low Riso can happen because of a poor ground (too dry) and, ileak when it's stormy weather, i think it's because of static electricity. Anyway, your message files shouldn't have to be empty, maybe your logger was writing when you shut it down or a SDcard that is slowly dying
