Hi folks, We ran a simple caget (once per second) from a linux host to an upgraded IOC. With the new rtems/3.14.12.7 IOC, it often experiences timeouts as shown below. With our legacy vxworks/3.13.9 IOC there are no timeouts logged. Relevant info is shown below. The caRepeater is running on the linux host. I'm thinking that setting the linux host EPICS_CA_ADDR_LIST=YES may help. I'm running that test now. Thank you for any insight, -Matt linux> cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) linux> uname -a
