texte = Donovan, Most of my servers are stable all year long, but I have one or two bad apples that hiccup and give me the "template not found" error. It always aggravates me that parts of my CMS will run fine, but only one or two pages say they are not found. Even though the WebDNA Monitor says the engine is running, I stop it and restart it to solve this issue. Other than the "template not found" issue, there's another issue that goes unnoticed until it's way too late. Emails get stuck in the EMailFolder without any other hint of a problem. When this happens, it happens to all websites on the server all at once. A WebDNA stop/start does not solve this issue, so I have to reboot the server. This has been a problem for me since 1997 when I started using WebDNA. Every server I've ever had, from WebCat 3 on RedHat 3, WebCat 4 on RedHat 4, WebDNA 5 on RedHat 5, WebDNA 6 on RedHat 5 and CentOS 6.2/6.3/6.4 have all randomly decided to one day trap all the emails. Well, in early 2014 a mission critical server for my utility company client stopped sending emails. It only took us about 18 hours to notice, but they were livid. So I developed a bunch of triggers, and set up a dedicated server just to ping every one of my production servers. Now, twice a day, all at once, I get a series of emails from all the servers sent to my smartphone. I know everything is working as long as I see every email. It turns out that this is a really good DNS and network check too. Now, the other issue, and the one you are wondering about with the command not working started happening in November 2014 with one of the servers. This one server is a VPS from GoDaddy. I think it started right after they upgraded it from CentOS 6.3 to 6.4. This server is running the WebDNA 6.? Pre-Gold build you gave me in the summer of 2013. I have a form page for uploading images. Once submitted the script runs this command: [text]garbage=[Shell scriptid=jr4newslettersimages][/Shell][/text] Normally the images are processed through ImageMagick and we see them on he screen. But several times a day since November the images do not upload. Here's the script that's getting called: "[PathToImageMagick]convert" -size [smThumb]x[smThumb] "../../../newsletters/images/original/[uploadedimg]" -resize [smThumb]x[smThumb] +profile "*" "../../../newsletters/images/thumb/[uploadedimg]"[unurl][line_ending][/unurl][!] [/!]"[PathToImageMagick]convert" -size [medThumb]x[medThumb] "../../../newsletters/images/original/[uploadedimg]" -resize [medThumb]x[medThumb] +profile "*" "../../../newsletters/images/medThumb/[uploadedimg]"[unurl][line_ending][/unurl][!] [/!]"[PathToImageMagick]convert" -size [lgThumb]x[lgThumb] "../../../newsletters/images/original/[uploadedimg]" -resize [lgThumb]x[lgThumb] +profile "*" "../../../newsletters/images/[uploadedimg]"[unurl][line_ending][/unurl] Of course that script has not changed in years, so that's not the problem. Just like the "template not found" issue, a stop/start of the engine fixes this. I assume it's some strange disconnect with the OS 6.3 to 6.4 upgrade, perhaps a library. I also assume it will go away when I eventually upgrade to WebDNA 8. In the mean time I just have a cron job running this script every hour during normal business hours: /etc/rc.d/init.d/WebCatalogCtl stop sleep 5 /etc/rc.d/init.d/WebCatalogCtl start I love my cats, but I always seem to find new ways to skin them. ;-) -Matt On 1/20/2015 9:33 AM, Donovan Brooke wrote: > Hi Matt, > I have experienced the “template not found” error, currently only on my 6.2 Server boxes.

The engine is pretty much the same between Server and FastCGI, only FastCGI restarts itself inherently, without the need of a WebDNA Monitor app. If you have a server that is crashing, you may not notice things as much, but the event would still be recorded.. and things like sessions, or page loads could still be interrupted.

Maybe not bad code necessarily, but maybe task-oriented code that WebDNA fails to execute through in an ideal/complete fashion. I think the answer would eventually come in a keen eye on the WebDNA and Apache logs, and trying to isolate an exact time when WebDNA stops recognizing a file. > > Anyway, I’d be interested if you find anything, as I was aware of the “template not found" issue, but it was never a priority because of the rarity of the event. > > Sincerely, > Donovan > > > > > On Jan 20, 2015, at 5:23 AM, Matthew Perosi
