-Are you sure this is 10 minutes rather than 10 seconds? nscd(1M) claims:
- Each
- cache has a separate time-to-live for its data; modifying
- the local database (/etc/hosts, and so forth) causes that
- cache to become invalidated within ten seconds.
-And this is consistent with the definition of 'check-files' in nscd.conf(4)
-and the presence of 'check-files passwd yes' in our nscd.conf.
-If something is happening with 10 minute periodicity, it sounds like
-an OS bug. Presumably it should be reported to Sun...
from nscd statistics
passwd cache:
Yes cache is enabled
5776 cache hits on positive entries
3 cache hits on negative entries
3814 cache misses on positive entries
109 cache misses on negative entries
59% cache hit rate
0 queries deferred
11 total entries
211 suggested size
600 seconds time to live for positive entries
5 seconds time to live for negative entries
20 most active entries to be kept valid
Yes check /etc/{passwd,group,hosts} file for changes
No use possibly stale data rather than waiting for refresh
that 600 seconds to live for positive entries may be the 10 minute
"window" for login problems?
