Hi there,
Since I enabled SMP mode on my squid 3.4.3 server, reconfiguring is not
working consitently. Here's the relevant log entries:
------------------

------------------
I find very strange that workers 6 and 5 try to get aufs cache stores.
They are supposed to be the rock store disker and the coordinator! My
squid.conf has:
workers 4
cache_mem 6144 MB
cache_dir rock /cache/shared 30000 min-size=1 max-size=31000
max-swap-rate=250 swap-timeout=350
cache_dir aufs /cache/worker${process_number} 25000 16 256
min-size=31001 max-size=346030080
logfile_rotate 4
Would squid be having troubles with my cache_mem and cache_dir big sizes?
Is squid -k reconfigure working well for everyone else with SMP?
Other strange entries, from earlier in the cache.log:
---------------------

---------------------
If kid5 is a disker, why does it setups up dns resolver and ldap auth
helpers? It looks like disker and coordinator try to process all
squid.conf directives, even when they are supposed not to do any
network-related stuff.
Should I try to "hide" those directives from them?
I also got something strange on shutdown:
----------------
2014/06/02 14:36:47| Set Current Directory to /cache
2014/06/02 14:36:47 kid6| Preparing for shutdown after 0 requests

2014/06/02 14:36:53 kid6| storeDirWriteCleanLogs: Operation aborted.
-----------------
What means "not OK to rewrite swap log"? kid6 is the coordinator, it
shoud not mess with cache dirs!
