Hello,
DSYEVD is a linear algebra routine. It is hard to judge where the error comes from without seeing the output and probably the input. The input can be sent to the Turbomole support if you do not what to place it on a public forum like this one here.
My first guess for this quite old Turbomole version is that you ran a small input in parallel on too many CPUs ??
Regards,
Uwe
