Well in situations like this (reboot performed) one can only offer suggestions from experience.
With uptime at +150, multiple zones and multiple Oracle instances I would be looking at two things.
1. Check the content of /tmp directories on all zones to see if one of them has five million files in it. If so, do we know why? Cleaning them up often clears the issue. If this is the problem (an O/S problem) then I would expect the problem to recur in the short term.
2. What is the setting of the parameter "pg_contig_disable" in the /etc/system files? On a long running uptime and Oracle instances, memory can become very fragmented and if Oracle dB requests contiguous memory then the system virtually hangs whilst working sets are shuffled to give Oracle what it wants. The cure is either to increase memory size or allow Oracle to use non-contiguous memory. If this is the problem (an Oracle problem) then I would expect the problem not to recur in the short term.
This really isn't very helpful I know, just thinking aloud.
