Yes, it may be an unresponsive server but the end
product is a user job crashing according to our users. Some
of those connections (later retried) would lead to success.
We can switch to level 3 and see as soon as we can design a
large scale test: we also have flukes with authentication
in general I have not reported this yet (I beleive it to be
LDAP related as changing the LDAP setup changed failure rates
from 50% to 3% ... but I cannot drop below the 3% failures).
In general, could someone indicates what is the most
reliable setting for Xrootd to retry upon failures (regardless
of delays this may cause) ??
Thanks,
