Hi Michael,
Recently I found that in cothread, if there is an exception in caput(pv[], value[],...), cothread captures the first error message only.
Is there a solution to get all reported errors?

For example, I have a bo record as:

record(bo,"testExample") {
    field(ZNAM,"ON")
    field(ONAM,"OFF")
}

Python code:
import cothread.catools as ca
# testExample2 does not exist
pv = ['testExample','testExample2']
value = ['one','zero']
try:
    res = ca.caput(pv, value, wait=True)
except ca.ca_nothing as e:
    print(e)

The except reports only:
testExample: Channel write request failed

If put the testExample2 first like:
pv = ['testExample2','testExample']

the get:
testExample2: User specified timeout on IO operation expired
