I applied the patches above, and the web test now hangs
I am reverting to my unpatched checkpoint and will eliminate the 118855-15
patch on the next iteration

Subject: hangs on sol10u2 and sol10u1 x86 (afterpatches)
Sun managers, I'm posting this thread I originally opened on the Dtrace list
- hopefully someone has seen this before:
To: 'Solaris Dtrace List'
Subject: RE: [dtrace-discuss] apache hangs on sol10u2 and sol10u1
(afterpatches)
The plot thickens - the hangs re-appeared after applying the recommended
patches to sol10u1
At this point I have re-installed sol10u1 and checkpointed the non-hanging
webserver (no patches) with a Flash archive and I have a raidctl mirror sync
in progress.
Once the mirror is synced up, my plan is to
1) break the mirror
2) apply the kernel patch, or next in recommended list
3) reboot, re-run the web test
4) if HANG report to SUN (on the open case) - this patch breaks web server
5) else repeat 2-4 with next patch in the list
Hopefully I will isolate what I suspect is a bad patch
Stay tuned...

Subject: RE: [dtrace-discuss] apache hangs on sol10u2 not sol10u1
So I tarred up the apache install and dropped it on a sol10u1 server - it
runs perfectly clean - no hanging web/svn operations
Maybe I'm guilty of jumping on U2 too quickly before the first round of
patches?
Still have the Sun case open - but I think I'll need to downgrade to U1 for
operational time constraints.

Is this a system or web server hang? Assuming the web server is hung, what
does pstack print when you run it against a hung process?
