>          Key: DERBY-1233
>          URL: http://issues.apache.org/jira/browse/DERBY-1233
>      Project: Derby
>         Type: Bug

>   Components: Network Server
>     Versions: 10.1.1.2
>  Environment: This can be consistently recreated on at least 2 machines that run our nightly tests.  We have not tried it on other machines yet.  The 2 machines environments are:
> 1) OS = SuSE Linux Enterprise Server 9     JAVA =  J2RE 1.4.2 IBM build cxia32142-20050929 (SR3)
> 2) OS =  Red Hat Enterprise Linux AS release 4 (Nahant)   JAVA = ava version "1.5.0_06" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05) Java HotSpot(TM) Server VM (build 1.5.0_06-b05, mixed mode)
>     Reporter: Barry Myers
>     Priority: Critical

>
> We run a rather large set of regression tests each night.  This will probably stress Cloudscape we we do make a great deal of calls to the database.  At some point in our
> tests they start to fail.  If the tests are separately and not back to back they will pass it seems that it is running alot of tests all at once that causes this problem.
> com.ibm.ac.si.ap.service.ServiceException: ACUASI0139E SQL Exception: A communication error has been detected. Communication protocol being used: Reply.fill().

> We have run our tests with the following derby settings:
> derby.drda.traceAll=true
> derby.stream.error.logSeverityLevel=0
