[squid-users] Squid 3.5.10 ldap helpers can't "reconfigure"

[Fabio Almeida]

Hi folks,

I have and Squid 3.5.10 instance that I can't reconfigure, it crashes if
there's many spawned ldap helpers.
But, if there's not many people connect it reconfigure normal as expected.

It's running on a FreeBSD 10.1-RELEASE-p19 amd64 with the following
./configure line:

./configure --with-default-user=squid --bindir=/usr/local/sbin
--sbindir=/usr/local/sbin --datadir=/usr/local/etc/squid

There's a total of 439 ldap group helpers enabled.
For user's authentication there's 127 helpers enabled.

It works as expected, except when um run "squid -k reconfigure", it crashes.

Is there a 'magical' total number of helpers it can manage?
Found on squid bug track system that it was related to 'Kqueue', so
recompiled without 'Kqueue' but the bug persists.
I'll collect the logs to send as soon as possible.

Any directions will be appreciated.

Thanks in advance,
