When doing an graceful restart, I sometimes get errors on my clients. When testing with the "Apache JMeter" stress tool with 50 parallel HTTP clients, I get different errors from JMeter like: - Connection reset by peer: socket write error - host.domain.com failed to respond - SSLHandshakeException: Remote host closed connection during handshake This happens on about 10% of my graceful restarts. If this happens, 1 or more parallel HTTP connections are affected.

Hi! Can you give us a bit more info about your settings? What MPM do you use? What it is its configuration? Is there an easy way to reproduce the issue? Thanks!

Hi, We use Apache as a reverse proxy. Configuration is one virtual host with HTTPS. We use mod_proxy and mod_proxy_balancer. The MPM is mpm_winnt and its config is: ThreadsPerChild 250 MaxRequestsPerChild 0 <nothing else> To reproduce: Just run a stress test like Apache JMeter or Apache Bench on one existing location and keep it running. Then graceful restart Apache using command "httpd.exe -k restart -m Apache -d C:\path\to\apache" The restart allways succeed but in some cases the stress test shows some connections errors. Thanks for your help
