Hari Hendaryanto:
yes, i think the disk I/O was to busy to handle postfix and view
http services. is the "delayed" psc_cache_update doing any harm?if
not, i can live with that (or at least i should figure out how to
tune the disk I/O latency)
If this happens often then it will impact Postfix performance, but
only if your server handles many connections (with 100 ms to access
the database, postscreen can handle up to 10 connections per second).
i reduced default_process_limit lower than its default value. the
warning goes away.
i'll monitor the maillog to the next view hours.
Perhaps postscreen should warn when the *average* delay goes over
some threshold. That would reduce the number of false alarms.
Maybe I can slip this in before the stable release.
