If your simulation stops at 0 seconds, then it might be caused by some error in intialize() function.
Something that is impossible to be executed.
I had the same error when i was trying to get the transmission level.

It seems your database may have become corrupted. This article gives some good examples of how that may have happened.
In summary, it might be due to hardware failure or software error. Apparently it sometimes happens when there is a large amount of traffic to your database.
If you don't have a backup of your database, you might have to recreate it from scatch.
Something else you can try is PRAGMA integrity_check. That will show you a little more info about what might be going on.

Trouble with errors in local Sugar instance

I'm having a problem with setting up a local Sugar instance on localhost in a vagrant VM. I created a local host instance from a backup file, which worked well the first time I tried it. But, after restarting vagrant about two weeks later, I get an empty grey screen and an error in the PHP log:
PHP Fatal error: Uncaught Error: Class 'Ramsey\\Uuid\\Uuid' not found in /vagrant/src/Cache/Middleware/MultiTenant/KeyStorage/Configuration.php:44
I deleted this instance and created another one from a different backup file. Again, it worked well initially. But after restarting vagrant today, I got the same error. This time, I looked into this error in more detail and managed to fix it by changing the use statement in Cache/Middleware/MultiTenant/KeyStorage/Configuration.php to "use Rhumsaa\Uuid\Uuid" (https://github.com/ramsey/uuid/issues/217). But now I'm getting a new error:
Uncaught Error: Class 'LoggerManager' not found in /vagrant/include/entryPoint.php:121\nStack trace:\n#0 /vagrant/index.php(17): require_once()\n#1 {main}\n thrown in /vagrant/include/entryPoint.php on line 121
This leads to 3 issues that confuse me at this point:
1) Why is this error thrown when a LoggerManager class does exist in include/SugarLogger/LoggerManager.php?
2) It seems that there is a more fundamental problem with this instance that prevents it from finding existing classes. I was thinking it might be a permissions issue and ran the commands to set the required permissions (using vagrant:vagrant instead of apache:apache), but it had no effect on the error. What else can I try to troubleshoot this?
3) Why did this instance work well initially and started throwing errors after restarting vagrant?
Thank you for any help!
I haven't been able to figure out what the problem was, but it went away after I set up a new local instance using a backup of a newer Sugar version.

What does it mean if a JDBC driver is unable to find a particular class

I work with reports and currently seeing a warning in my BIRT designer(Eclipse) error logs:
"Cannot load driverClass: org.apache.hive.jdbc.HiveDriver"
I have dealt with classnotfound issues before and usually updating the correct driver resolved the issue, but this time the report is working and still, this warning is shown in error log and I am trying to understand why.
Looking at the below message it seems the oda driver is looking for
"org.apache.hive.jdbc.HiveDriver" class and unable to find it.
java.lang.ClassNotFoundException: org.apache.hive.jdbc.HiveDriver
cannot be found by
com.actuate.data.oda.jdbc.drivers_24.2.1.v201710020253
Please help me understand the warning message and how can I get rid of this.

[Error]: Failed to run command with error: Error Domain=Parse Code=428

I get this error sometimes when trying to save things to Parse or to fetch data from it.
This is not constant and appear once in a while making the operation to fail.
I have contacted Parse for that. Here is their answer:
Starting on 4/28/2016, apps that have not migrated their database may see a "428" error code if the request cannot be handled by the remaining shared pool of resources. If you see this error in your logs, we highly recommend migrating the database for your app without delay.
Means this happens because of starting this date all apps are on low priority but those who started DB migration. So, Migration of the DB should resolve that.

Debugging PL/Python functions

I just practiced some happy engineering and wrote lots of code without testing each step as I usually do.
So now I have a few hundred lines of code with an error somewhere... I am using pgAdmin III to write the Python and I write it in their Query Tool, which is used for normal SQL queries. I will not past my Python code as I do not want help with this specific problem. Instead I am after a tool, which will provide me with the exact position in a PL/Python function where the error occurred. To see my reason for wanting this, the following is the error message I am getting, and I have way of debugging where the error occured:
********** Error **********
ERROR: invalid input syntax for integer: "atextstring"
SQL state: 22P02
I've been using PL/pgSQL for a while and I haven't found a debbuging tool.
