Hello    I am doing analysis using a large data set.  I am trying to do generalized linear mixed model with two random intercepts, one for the zip code of the patient and one for the treating hospital.  Here is the code: 31 32 proc glimmix data=dataname noclprint pconv=0.001 ; 33 class variables ; 34 model thirty_mortality= variables 39 /solution dist=bin link=logit; 40 random intercept / subject = variable1*variable2;   44 run;     initially it was giving me a message that there is not enough memory  so I increased the memory with memsize run option to 6 gb   now the model converge (it gives message that convergence criterion satisfied)  then it gives the following error: ERROR: An exception has been encountered. Please contact technical support and provide them with the following traceback information: The SAS task name is [GLIMMIX] ERROR: Write Access Violation GLIMMIX Exception occurred at (7E36FE97) Task Traceback Address Frame (DBGHELP API Version 4.0 rev 5) 00007FF97E36FE97 00000006CFEFE040 sasglimm:tkvercn1+0x19EE57 00007FF97E22CFF3 00000006CFEFE290 sasglimm:tkvercn1+0x5BFB3 00007FF97E22C541 00000006CFEFE380 sasglimm:tkvercn1+0x5B501 00007FF97E321D2B 00000006CFEFE4D0 sasglimm:tkvercn1+0x150CEB 00007FF97E1D29C6 00000006CFEFF950 sasglimm:tkvercn1+0x1986 00007FF9930DF5A8 00000006CFEFF958 sashost:Main+0x15268 00007FF9930E59CC 00000006CFEFFC80 sashost:Main+0x1B68C 00007FF9CD507BD4 00000006CFEFFC88 KERNEL32:BaseThreadInitThunk+0x14 00007FF9CEE8CE51 00000006CFEFFCB8 ntdll:RtlUserThreadStart+0x21     Can somebody help please?   thanks     ...
