This looks like a benign glitch in EPICS R3.13. It appears that one
thread called the connect() system call briefly after another thread
closed the socket.

Your observation that a hard reboot fixed the problem, and a soft reboot
did not, does not immediately point to a software problem.

Have you seen this situation occur more than once? Which version of
EPICS was running?

Title: S_errno_EINVAL

Hi,

Can someone tell me what the following error message means:

CAC: Unable to connect port 5064 on "10.2.2.106:5064" because
22="S_errno_EINVAL"
dbCa:exceptionCallback stat Network connection lost channel unknown

10.2.2.106 is the IP of another crate where the system is supposed to
get a value. The system did not work properly when rebooted with a
CTRL-X, but it started to work fine after a hard reset.

Pedro.
