Hi Eliezer,
I dont now if 3.3.x and 3.2.x *really need* more helpers to work, I
just saw here http://www.squid-cache.org/Doc/config/external_acl_type/
that now we CAN start more helper process, and as I have resources I
might start more of them just to have them up if needed in some point
of time. So,"its not a bug, its a feature" hehehe...
But, about having more then 1 rock store, I dont know, I may have made
some confusion when reading about SMP and cache_dir options diferent
then "rock", maybe THAT is what is generating the "FATAL:
Ipc::Mem::Segment::open failed to
shm_open(/squid-squid-page-pool.shm): (2) No such file or directory"
errors... I am not in work yet (had a long kernel's updates night) but
I will test with only one rock store to check how things go...
and, yes, ext_ldap_grou_helper is working like a charm, what is
already half of the way for me...
regards.
