PSSYGVX - LWORK parameter number 28 had an illegal value

Dear Intel Forum,

 I am trying to use PSSYGVX, however if a use a matrix larger than 5000 everytime the function returns:

   PSSYGVX  parameter number   28 had an illegal value
   The info parameter is -28

I tryed to use lwork = -1 (which i believe is the 28 parameter) to ask wich is the optimum value, even with this number a recive the same mensagem. Another values was tested without success. Please, this could be a memory issue ? There any way to debug this ?

 Best regards
