Hi Jeff and others,
I see strange crashes of the CA gateway which probably originate in the CAS code.
If I use an explicit port in EPICS_CA_ADDR_LIST like this
EPICS_CA_ADDR_LIST="gateway:5066"
and then start a softioc running a record with an INP link to a record behind
the gateway (running on that port), the gateway starts printing errors and
refuses to handle any more requests. It has to be restarted.
The gateway prints:
CAS: CAS Request: ? on pc3853.psi.ch:38210: cmd=13 cid=0 typ=11 cnt=5064 psz=0
avail=81818260
Oct 12 14:01:36 !!! Errlog message received (message is above)

....
However, a simple caget works without problems, at least before the softioc
crashes the gateway.
I tried 3.14.8 and 3.14.9 on the ioc side. The gateway runs with some pre-3.13.9
CVS snapshot. But I also tried it with the 3.14.9 libraries.
BTW: I could not recompile the gateway with 3.14.9, because the function
epicsNTOH16 does not exist any more. I had to trick the 3.14.9 libraries into
the gateway's library search path.
Please, don't remove API functions when changing Channel Access!
Any idea?
Dirk
