Hello all,I recently had to switch from prefork to worker on a large production system, in order to optimize performance and limit memory usage under high load.
In principle, it is working fine, however I see that over time some processes are "hanging" even though they should have been killed off (recycled).
The worker table in server-status looks like this: W....G........WW.....GW......................................... ..........W......W.............................................. ..........W.......W............................................. ............WG..........W....................................... ....................W........................................... ..........W..WW.WWW....W........................................ WWW_____W_____________W_W....................................... __________________W______....................................... ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ ................................................................ ................................................................My question is: Will the top 6 processes be killed "for real" at any stage, or will the server stop accepting connections once the remaining processes have gone into the same state? I can manually kill off the hanging processes (kill -9), but this is risky at best as I don't know the PIDs (and am unsure how to find this information).
About the setup: HP DL385 dual dualcore opteron servers FreeBSD 6.1-RELEASE Apache version 2.0.58_1 Mod_jk version 1.2.15 Tomcat version 5.5.12_3The apache server is configured with the minimum number of modules, no PHP or other sensitive stuff. The only indication I have on where the problem may lie is that I haven't been able to reproduce when simulating load on a path that isn't mod_jk-mounted, however reproducing has proven difficult in any case.
Does anyone have any suggestions? Or am I worried without reason?
