FYI, very recently people have reported some new bugs/problems running
AOLserver 4.0:
Restart problems,
multiple people reporting having to send a kill signal twice with a
pause in between and/or kill -9. Sounds like a problematic and
annoying bug but not a show-stopper for most people.
One or two people also seem to be reporting AOLserver 4
respawning infinite times
until the box comes to a halt. It is somewhat unclear, but it appears
that this is likely due to attempts to remotely exploit an as yet
unpatched security bug AOLserver 4.0, and those (presumably
unsuccessful) attempts had the effect of a DOS attack. Supposedly
this hole is very difficult to exploit successfully, an it is thought
that the bug does not exist in AOLserver 3.3+ad13, but AFAIK no one
has double checked and verified that.
On a more pleasant note,
Zoran recently announced
some promising alternative Tcl interp initialization work giving
reportedly 1/3 the memory footprint and 50 times faster thread startup
than baseline in AOLserver 4.0.
