Experimental Physics and Industrial Control System
Jeff,
The think the problem might have been caused by EPICS launching a second copy of my IOC instead of caRepeater one time. So there were two copies of the IOC application running, causing the IP problem?
There is something else I don't understand about caRepeater behavior on this IOC.
Here is a list of cygwin processes before I start my IOC.
$ ps -a
PID PPID PGID WINPID TTY UID STIME COMMAND
1364 1 1364 1364 ? 18 20:29:52 /usr/bin/cygrunsrv
1660 1364 1660 1672 ? 18 20:29:57 /usr/sbin/sshd
I 460 1 460 460 0 11092 20:31:24 /usr/bin/bash
2280 1 2280 2280 1 11092 14:02:41 /usr/bin/bash
3808 2280 3808 2740 1 11092 14:03:38 /usr/bin/ps
Now I start the IOC. Note that the path to caRepeater in EPICS base is in my cygwin PATH. Now list the processes again.
$ ps -a
PID PPID PGID WINPID TTY UID STIME COMMAND
1364 1 1364 1364 ? 18 20:29:52 /usr/bin/cygrunsrv
1660 1364 1660 1672 ? 18 20:29:57 /usr/sbin/sshd
460 1 460 460 0 11092 20:31:24 /usr/bin/bash
2280 1 2280 2280 1 11092 14:02:41 /usr/bin/bash
I 2112 460 2112 3008 0 11092 14:03:49 /cygdrive/j/epics/devel/dxp/2-4beta/bin/cygwin-x86/xmapApp
736 2112 2112 3284 0 11092 14:04:49 /cygdrive/h/epics/base/bin/cygwin-x86/caRepeater
3932 2280 3932 3456 1 11092 15:14:12 /usr/bin/ps
xmapApp is the IOC process. Note that starting the IOC has started the caRepeater, as it should have.
However, I get the following message from iocsh on the IOC after iocInit is complete.
*****
CA client library is unable to contact CA repeater after 50
Silence this message by starting a CA repeater daemon
or by calling ca_pend_event() and or ca_poll() more often.
******
This does not seem right. Why am I getting that error message even though caRepeater was in fact successfully started?
Thanks,
Mark
