Lily Wei updated DERBY-3746:

                derby_mailsdb_XSDG9.log

Hi There:
     Yes, the mailjdbc Refresh thread will be interrupted by Browse thread if it is finishing
the doWork() method and the thread is sleeping.  I also see XSDG9: Derby thread received an
interrupt during a disk I/O operation.
ERROR XSDG9: Derby thread received an interrupt during a disk I/O operation, ple
ase check your application for the source of the interrupt.

iner4.java:244)

      The derby.log and mailjdbc_patch022410.diff is attached.
      The mailjdbc_patch022410.diff include take out select from Refresh.java, change the
browse mail to read message and read attach message. Add more sleep between thread to avoid
deadlock.

> Hi
>  
> Following exception occurs while running our application with embedded derby database.
The application uses multithreading. This exception occurs while insert query is executed.
The insert query is run using JDBC:
>  
> insert into sign (sign, month, day, offset, digest) values (?,?,?,?,?). 
>  
> The table for which insert query is fired is:
>  
> create table sign(ID  INTEGER NOT NULL GENERATED ALWAYS AS IDENTITY PRIMARY KEY, sign
varchar(32), month char(6) not null, day char(2) not null, offset bigint not null, digest
varchar(32) for bit data not null)
>  
> There are multiple threads inserting data in database. I tried to search a lot on net
but could not find any solution. We're using derby 10.3.1.4. Not sure about the root cause.
It will be great if anybody provides some solution because it is creating lot of problems
in our application.
