Re: ca client get waveform pv error

> 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
