Data leaked a buffer with ID 1 of type 1

We are using a datareader component to retrieve data from a Pervasive 8.6 database. We have four separate datareader components in various packages retrieving data into our datawarehouse in SQL2005. One of the components has started to fail regularly with the following error.

The other components run without any problems as did this one up until we installed service pack 2. We then started getting these occasional failures. Any thoughts on what is happening here?

Thanks,

Do you have package logging turned on? The PipelineBufferLeak, I believe, is a warning, not an error, and hence would not stop execution.

Turning on package logging might help get a more clear error message....|||

I do have logging turned on and the error in the log is more vague than within the job history. I'm copying in the first rows indicating the error from the log. The execution is halted due to whatever error is happening.

|||Make a copy of that package and strip everything out of the data flow except for the data reader source. Then hook it into a row count transformation. Re-run the package. What happens?|||The job ran successfully returning 64 rows. However, the package doesn't fail regularly so the fact that this instance ran successfully probably won't offer much. I will load this abbreviated package to the server and schedule it in the same time frame as the current package, which fails with the buffer leak error. I'll turn logging on to capture whatever message might come across.|||

The only reason I suggested this is because the error message returned is a DataReader failure message, so this takes out all processing that might unduly influence things. Can you use something other than a DataReader Source? OLE DB Source, for instance?|||

I see your point regarding isolating the datareader. As recommended last week, I deployed a package which performs the query and dumps to a rowcounter. We get the same failure as the regular job. Both jobs failed on one day (Sat). It ran fine on Sun and Mon. Here are the error rows from the logger: I'm wondering if we are getting a timeout on this query as it is a more complex query than the other three jobs running against the DB.

Regarding an alternate driver, the Pervasive OLE DB driver is very unstable in the SSIS environment and so it can't be used at all. We are looking at the timeout value to see if the Pervasive ODBC driver can be tweaked.
