 Description   

I'm performing around 600 inserts with 3 values (unsigned long long, unsigned long long, long) each in bulks of 10 inserts within 2 or 3 sec. And usually get 1 to 6 corrupted inserts (some bit seem to shift). Not sure if it is a server or connector problem. I tested with server 10.2.4 and connector 2.3.3 and also connector 3.0.1.

Maybe related to CONC-240 ?

Hi Thomas,

could you please provide a short code snippet to repeat the problem ?
Thanks!

Connector/C 2.3.3 doesn't provide bulk, the latest versions for bulk are in 10.2 branch (server) and master branch (Connector/C)

After creating a repro case I realized that this was in fact a problem of my CONC-240 workaround. Sorry! Everything works (I thought Server 10.2.4 comes with connector 2.3.3).

Thanks for the info. Closing this bug as "duplicate" of CONC-240
