I traced it down to ca_add_masked_array_event/ca_create_subscription as well. In a recent run, I had 14 out of 2600 sequences not getting their monitor callbacks. I did a dbel on the non-functioning PV’s (H75 H73 H82 H78 H72 L52 L54 P93 R71 R80 V82 V71 V86 Z80) and a couple of functioning ones (A01 A75). The results are pasted below. The ones that are not getting their monitor callbacks called seem to have a fair number of “undelivered” or “discarded by replacement” messages. The ones that are functioning have “queue empty”. Is this expected? Any suggestions as to next steps for debugging are appreciated. Regards, Murali epics> < /tmp/dbel.txt dbel H75 10 1 PV Event Subscriptions ( monitors ).
