Subject:	CA problem w EPICS 3.14.11 & VxWorks 6.7

Hello,

We have 2 IOCs running EPICS 3.14.11 with VxWorks 6.7.

Any record on an IOC with a CA link on a record located in the other IOC stays UDF=1 forever. This problem arises with EPICS_CA_AUTO_ADDR_LIST= YES.

With EPICS_CA_AUTO_ADDR_LIST=NO and EPICS-CA-ADDR-LIST= … it works. But we would like to avoid to have this parameter to “NO” and having to maintain the host list in ADDR-LIST.

Especially in the case where:

On IOC1 : EPICS-CA-ADDR-LIST=<IP IOC2>

And on IOC2: EPICS-CA-ADDR-LIST=<IP IOC1>

(needed for CA links in both directions)

We have “CA beacon routing … ECONNREFUSED” on the 1rst booted IOC.

We did’nt have this problem with the previous release.

This problem arises also with CA links between VxWorks an Linux.

On the other hand, no problem with CA links between 2 Linux IOCs

Thanks Jeff (I think it is probably a problem for you . . .)
