server error on random occasions

[Manny S]

I have my application deployed onto App Engine.  When I access my application at times I get a server error. If I refresh the page the server error goes away.  Another time the app worked perfectly for me but a friend based out of a different city tried to access it and it kept giving him the server error for about half an hour. And then he was able to access the application. 

The error -  Error: Server Error - The server encountered an error and could not complete your request.

 If the problem persists, please report your problem and mention this error message and the query that caused it.

I did a search and there were a couple of posts that mentioned app.yaml formatting issues. I work on the Java side and so far my web.xml seems to be well formatted. If the formatting is bad wouldn't the error at least be consistent. Not sure why it happens occasionally. Any explanations or inputs on this issue would be greatly appreciated.

Your not alone I even got the same server error on Google own App
Engine Status page at http://code.google.com/status/appengine

My app also gets this error and it also takes a LONG time to load eve
when its loading the minimum, and this is after a few refreshes so the
excuse that its loading a new VM isnt valid.

Interesting...so does this mean that random server errors is something that we have to live with :) ?

Hi Manny,

It's impossible to say based on your description what the problem might be. Most likely, your application is throwing an exception - you need to check the request logs in your admin console to determine what went wrong.

Nick,

The server error occurs when I try to load any of my three main (simple) jsp pages (no database access etc). The error is not repeatable and the app works fine now. The error occurred twice this week. And once it was loading just fine for me but for a friend of mine based out of a different city it just conked out and gave the server error message. I checked the request logs in the admin console and it does not show me any errors. Plus my code is peppered with try catches that would take me to an errorpage :).  Would an exception cause such an erratic behavior. Would it not at the least be a bit more consistent. Any inputs will be greatly appreciated.
