Just another oddity to add to the issue.
Overnight several more hung threads appeared and the load on the system had
jumped into the mid 20's.After killing these the load did not drop. Looking at
the list of running processes I found httpd's running,spawned from the original
root httpd process that *were not even displayed* in the scoreboard!! After
killing these hidden zombies off the load dropped again.
So now I have to catch and kill two types: Zombies on the scoreboard and hidden
zombies.
And this is cute. Some times the zombies hang around so long that when the
system gets back to creating a new process for slot #1, if the zombie was
originally in that slot it is displayed their along with it's brothers for the
new process:
e.g. Note process 19597 below

Upgrade as in Apache upgrade or Solaris 5.10 patch upgrad? :)
Apache is all new of course 2.4.12 with the latest add on sources (apr, pcre,
etc)The bad news is the OS is not at all up to date. And for reasons I have no
control over, I cannot patch.So if this is an OS issue then ......
I seem to be running with the Sun Native LDAP SDK. Would building against
different LDAP source help? (Open LDAP)?
Long term plan -> moving all Apache servers to Linux

It is possible but IMO not very likely. It has to corrutp memory just
enough to put a looping structure in apr_rmm. What's your upgrade
history like?
