Depends on your setup of course but I see something like this in my arch.log right at the beginning.
<context class="com.cosylab.epics.caj.CAJContext">
<preemptive_callback>true</preemptive_callback>
<addr_list>gateway:5076 gateway:5077 gateway:5078 other-gateway:5064</addr_list>
<auto_addr_list>false</auto_addr_list>
<connection_timeout>30.0</connection_timeout>
<beacon_period>15.0</beacon_period>
<repeater_port>5069</repeater_port>
<server_port>5076</server_port>
<max_array_bytes>80000000</max_array_bytes>
<event_dispatcher class="org.epics.archiverappliance.engine.epics.JCAEventDispatcherBasedOnPVName"/>
</context>
I found it:
<context class="com.cosylab.epics.caj.CAJContext">
<preemptive_callback>true</preemptive_callback>
<addr_list></addr_list>
<auto_addr_list>true</auto_addr_list>
<connection_timeout>30.0</connection_timeout>
<beacon_period>30.0</beacon_period>
<repeater_port>5065</repeater_port>
<server_port>5064</server_port>
<max_array_bytes>30.0</max_array_bytes>
<event_dispatcher
class="org.epics.archiverappliance.engine.epics.JCAEventDispatcherBasedOnPVName"/>
</context>
One thing look's strange, max_array_bytes...Looks a bit low, can be the
problem?
pause/resume I tried
Pausing/resuming tears down and recreates the CAJ channel for the PV so if you are unable to connect even after this you probably have some misconfiguration; that is, you can rule out most transient errors.
IOC's log on ioc machine right
Yes; sometimes there could be stuck tasks on the IOC side; you can check for that.
Your PV Details page for this PV could have information there that could help. You can get to this using something like so - http://localhost:17665/mgmt/bpl/getPVDetails?pv=Your_PV
I take a look, but i can't see anything strange
Finally, would you be in a position to attempt a restart?
I will try it, but on next week.
The most strange thing is a lot of PV's work well, and a few has
problems (eventually disconnect)
Thank you again

This seems like it might be a CA client configuration issue
This is the most likely case. The engine prints out it's CAJ
configuration on startup and you should be able to see this in your logs.
I didn't find it. I find engine/logs/catalina.err, is there another
location?
You can try a couple of things. You can pause/resume the PV's in
question and see if they reconnect back. You can also look in the IOC's
logs and see if there is anything interesting going there.
pause/resume I tried. IOC's log on ioc machine right? apparently there
is no errors (on epics console).
