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) bad request code=13 in DG Oct 12 14:01:36 !!!

Errlog message received (message is above) 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 -- Dr. Dirk Zimoch Paul Scherrer Institut, WBGB/006 5232 Villigen PSI, Switzerland Phone +41 56 310 5182
