Well, most of servers are still stable but I just reproduced this issue on peak time,
One of mega servers was running 4.0.20 at the highest peak time, switched to latest 4.1.8 and boom ! CPU idle goes down to zero while it was about 50% before 4.1.8
switched back to 4.0.20 and load went down
I just see litespeed process after 4.1.8 at the peak time at the top,
It seems that its stable when we switch to 4.1.8 at off-peak time and it will be okay when it got traffic peak, but during traffic peak switching to 4.1.8 kills the server easily while 4.0.20 is okay
I guess starting 4.1.8 with high traffic and request leads to this issue
George, seems that its not addressed yet, at least in this case
Please let me know how to provide debug information to you? is it necessary to install dbg version and enable DEBUG to have core dumps enabled? or just change log level to DEBUG?
Hope that we can find the right solution finally
