Gearman on Dreamhack
Has anyone got any hints on getting Gearman working on a Dreamhack? I keep getting this: '[Error: Unable to get gearman client. @ hack.dreamwidth.net]'

and it looks like you have 3 CC gearman workers trying to connect to gearmand, and gearmand is eating oodles of CPU. That doesn't sound healthy. Kill all 4 processes and make sure they're dead, restart gearmand, and go through the checks again:
cat $LJHOME/temp/gearmand.pid
netstat -A inet -a -n -p | grep 17096
ps auxww | grep -i gearmand
Then, start apache, and start 1 (and only 1) worker process (either shop-creditcard-charge or shop_creditcard-charge.PROPER, depending on which you need), in verbose mode.(or shop_creditcard-charge.PROPER).
Test it, and see if things work better. (You should be getting messages from the worker process. Paste them in your reply, and ^C to kill the worker when you're done.)
I haven't tried running the shop worker, but I've been able to test sysban gearman processing, and it worked without a hitch. My guess is that something (perhaps the three shop worker processes) was messing things up. If you still have problems, I'll walk you through a test using sysban, so we can make sure your basic gearman configuration works.

Re: the saga continues...
Once you've identified the process ID ('ps -aux' will get you a list of the full set of processes running on the machine), "kill [processid]", then wait. It should then be gone when you list the processes again. If it isn't, you might need to wait a few minutes and issue the kill again; if that doesn't work, "kill -9 [pid]" will get rid of a really stuck process, but you should reserve that for the stubborn ones, since it forces an exit and doesn't do a graceful shutdown.
