Re: runtime error

Hi Mark,
Apart from the ADDR_LIST, I have:

EPICS_CA_CONN_TMO: 30.0
EPICS_CA_AUTO_ADDR_LIST is undefined
EPICS_CA_REPEATER_PORT: 5065
EPICS_CA_SERVER_PORT: 5064
EPICS_CA_MAX_ARRAY_BYTES: 16384
EPICS_CA_AUTO_ARRAY_BYTES: YES
EPICS_CA_MAX_SEARCH_PERIOD: 300.0
EPICS_CA_NAME_SERVERS is undefined
EPICS_CA_MCAST_TTL: 32
EPICS_CAS_INTF_ADDR_LIST: 239.128.1.6
EPICS_CAS_IGNORE_ADDR_LIST is undefined
EPICS_CAS_AUTO_BEACON_ADDR_LIST: NO
EPICS_CAS_BEACON_ADDR_LIST: 239.128.1.7
EPICS_CAS_SERVER_PORT is undefined
EPICS_CA_BEACON_PERIOD: 15.0
EPICS_CAS_BEACON_PERIOD is undefined
EPICS_CAS_BEACON_PORT is undefined
EPICS_BUILD_COMPILER_CLASS: gcc
EPICS_BUILD_OS_CLASS: Linux
EPICS_BUILD_TARGET_ARCH: linux-x86_64
EPICS_TZ: CST6CDT,M3.2.0/2,M11.1.0/2
EPICS_TS_NTP_INET is undefined
EPICS_IOC_IGNORE_SERVERS is undefined
EPICS_IOC_LOG_PORT: 7004
EPICS_IOC_LOG_INET is undefined
EPICS_IOC_LOG_FILE_LIMIT: 1000000
EPICS_IOC_LOG_FILE_NAME is undefined
EPICS_IOC_LOG_FILE_COMMAND is undefined
IOCSH_PS1: epics>
IOCSH_HISTSIZE: 50
IOCSH_HISTEDIT_DISABLE is undefined

Until recently, I had EPICS_IOC_IGNORE_SERVERS=rsrv also.  Why are there 
no PVA environment variables?
We are working on turning off rsrv and moving strictly to multicast.
Cheers,
Pierrick
