I'm thinking about that, because the single squid core is 100% CPU
I tried with 900MB and 50MB without more success, I also added sslflags-NO_DEFAULT_CA

How much simultaneous users do you have ? and bandwidth ? 

I'm using this right now, the number of process used is very better now but still an issue with CPU  

acl nobump dstdomain "/home/squid/domains"

http_port 8080 ssl-bump cert=/etc/squid/ca_orion/cert generate-host-certificates=on sslflags=NO_DEFAULT_CA dynamic_cert_mem_cache_size=500MB
sslcrtd_program /usr/lib/squid/ssl_crtd -s /usr/lib/squid/ssl_db -M 500MB
sslcrtd_children 1000 startup=100 idle=5

sslproxy_capath /etc/ssl/certs/
sslproxy_foreign_intermediate_certs /etc/squid/ssl_certs/imtermediate.ca.pem

acl step1 at_step SslBump1
ssl_bump peek step1 all
ssl_bump splice nobump
ssl_bump bump all

Maybe there is a problem with memory, but as you can see here CPU is the point

Amos, there is way to add the domain requested in message like this ?

2018/03/21 09:45:30| Error negotiating SSL on FD 1835: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed (1/-1/0)

It can be very, very, useful for analysis 

Thanks
