I am not sure how CA allocates memory, but you have set a REALLY big value for EPICS_CA_MAX_ARRAY_BYTES (1.6GB). Perhaps you should try setting it to be just a little bigger than the largest image you will use. Is your data 8-bit? If so then 400000 is big enough for the 640x480 array you mentioned.Hi,Mark: When I change EPICS_CA_MAX_ARRY_BYTES to 400000 as your suggestion, the clients works ok, It seems that I set the environment variable too large, and the client can not allocate so much memory. thanks for your help,and I found if I set the variable to 1600000000,the IOC will consume 1.6G memory too,I find it perviously but I didn't know it is because I set the variable too large, Thanks ,my problem solved, ^_^ Best Regards wantianmin
