PC Server causes core dump

Description

Once in a while the pc_server causes a core dump on the system. We see just before the core dump:

1) In pc_server_6991.log the message is
pc_server_write_log.c: Value too large for defined data type

2) The corresponding file pc_ser_6991 is not rotating and there is no write activity to this file

3) The pc_ser_6991 is approx 2,1 G (is this a limit in Aleph ?)

4) The pcserver itself remains functional and does not crash but becomes slow

We restart the pc server and everything is normal without errors.

Resolution

In the GUI in acquisitions/serial module ...

schedules
the value 0
in the field Issue No. (Enum.b)

... makes the GUI to hangup the PC and it keeps the connection to the pc-server open and will not disconnect.

After a view actions like this there are no free pc-server processes left and nobody can work with the QUI anymore util I reset the pc-server.

We solved the problem by editing manually table xxx50.z08

SQL>

update xxx50.z08
set z08_issue_number = 1
where z08_issue_number = 0
