General error;800 Implicit SERVERDB restart (connection aborted) ?

Folks;

always in for something new, today I experienced two crashes in a row in our MaxDB installation. Looking at our application log files, this seemed to happen following a certain SQL DELETE statement (always the same, with the same parameters):

SAP AG][LIBSQLOD SO][MaxDB] General error;800 Implicit SERVERDB restart (connection aborted) [S1000]

After that, the database instance needs to be restarted. It reproducibly happens whenever I try to execute this particular query. I do not really have an idea how to track this down. MaxDB is 7.8.02.28 on a Linux x86_64 system. Any comments on that issue greatly appreciated.

Thanks in advance,

Kristian
