Hi,
I'm running a CA client on IOC A accessing records on a IOC B. After
performing a ca_clear_channel on all the channels on IOC A connected to
the IOC B I receive this error:

CAC: unexpected select fail: 851971=S_iosLib_INVALID_FILE_DESCRIPTOR.

From what I understand about CA it appears the fd on IOC A which
handles the connection to IOC B has been released prematurely.
I found the errors source in src/ca/bsd_depen.c but am uncertain as to
how the select bits are set.
Any insights? Thanks
Geoff
