Re: [Handle-info] Help with java handle system client library

[Nicola Mezzetti <n.mezzetti@cineca.it>]

Hi Sean,
    I met the problem again, however I can exclude that it was a 
problem of permissions or a problem of disk space. As far as I 
understood, the problem occurs when one tries to store misformed handle 
values; in this case, the insertion obviously fails but it appears that 
the handle system cannot insert any further transaction (either correct 
or not) within the same transaction queue file.

    For both the times that error occurred, the workaround for the 
problem was to wait the next day and then to restart the handle system 
in order for another transaction queue file to be initialized.

    Now, I will try to understand whether it is a software problem or a 
problem caused by the transaction queue that gets corrupted. For the 
sake of precision, we still employ the handle system version 5.3. When I 
will find some spare time, I will check whether the problem occurs even 
with the current release. In any case, I will let you know more about this.

Thank you very much for your kindness and availability.

Best regards,
    nicola
