Folks,

I am writing to report a possible problem with base 7.0.4 on Windows.

Today I updated EPICS on a Windows machine from base 7.0.3.1 to 7.0.4.  This machine runs 3 EPICS IOCs; 2 are areaDetector camera IOCs and the third runs various serial and TCP devices.

The behavior I observed was strange.

- The first 2 IOCs to start worked fine, I could connect to them from Channel Access clients.

- The third IOC started fine, and dbl showed all the PVs.  However, I could not connect to them from any Channel Access client (medm ,caget, etc.)

If I changed the order in which I started the IOCs it appears that the last IOC to start is the one that cannot connect with Channel Access.

I rolled back to the 7.0.3.1 versions of the IOCs and they all connect fine.

I cannot say that I have conclusively proved the above by starting the IOCs in all different orders, etc.  But it looking like a problem.

Were there any changes in 7.0.4 that might have caused such a problem?
