[squid-dev] Ntlm helper child exceeds limit

[manojmaybe]

I have used squid 3.3 proxy server with NTLM authentication. I have use the
squid config file for  maximum of 3000 children.

auth_param ntlm children 3000 startup=0 idle=0

but when traffic is very high ,found that more than 3000 ntlm helper
children is active (used ps command to get the number of ntlm child process)
and helper child are going to be crash and showing error cache log
