Hello,I have a pretty much big process with approximately 1.000 steps. When I start the process I get the following exceptionrg.apache.ibatis.exceptions.PersistenceException: ### Error updating database. Cause: java.lang.IllegalArgumentException: NaN### The error may involve org.activiti.engine.im

The cause of this error is that the query of variables has exceeded the Oracle Database limit that IN Clause 1000 item limit.
If we use Oracle Database, we cannnot use IN Clause more than 1000 item.

> So the result variables which are stored in activiti variables are mainly numbers or arrays of numbers (which can reach large sizes - e.g. 8.000).
> I am working with Activiti version 5.17.0 on an Oracle 12c database.

The solution is that you reduce the number of variables of process.

The field not used for search should be stored as individual variables.
The field not used for search should be aggregated into one variable as binary variable type such as java.util.Map.

Thanks for your answer.

Even if I wanted to agree with you..

1) I haven't read any limitation about the number of process variables that activiti can handle.

2) Why it happens randomly? Why sometimes the process just finishes ok?

Seems from the trace you provided that there is an issue with a double value

Caused By: java.lang.IllegalArgumentException: NaN
at oracle.jdbc.driver.OraclePreparedStatement.setDoubleInternal(OraclePreparedStatement.java:6599)
at oracle.jdbc.driver.OraclePreparedStatement.setDouble(OraclePreparedStatement.java:6574)
at oracle.jdbc.driver.OraclePreparedStatementWrapper.setDouble(OraclePreparedStatementWrapper.java:193)
at org.apache.ibatis.type.DoubleTypeHandler.setNonNullParameter(DoubleTypeHandler.java:28)
at org.apache.ibatis.type.DoubleTypeHandler.setNonNullParameter(DoubleTypeHandler.java:23)

It's hard to understand the issue if there is no way to reproduce it. Can you try to reproduce using a simpler process definition? I would also recommend you to try the latest activiti version (currently either version 6 or 5.22).
