9.510-5 Web Filtering

rsenio

Anyone running 9.510-5 with web proxy, AD SSO, and HTTP scanning? I'm seeing lots of 

function="ssl_raw_read" file="ssl.c" line="816" message="SSL_ERROR_SYSCALL: ret=-1 error=Connection reset by peer"

in the logs. Anyone else seeing this?

    I'm not noticing any related issues, are you?

    This started in my lab logs on 1 August.  9.510-4 was installed on 30 July and 9.510-5 on 7 August, so I suspect a pattern update on 1 August before 13:00 UTC.

    Cheers - Bob

    NB 2.5 hrs later: There were two updates each of savi and avira patterns about 20:13 UTC on 30 July.

    I also have a lot of connections reset by peers after updating the firmware. three times so far today. I don't know if there's a correlation, but in my case I'm running in transparent mode with no authentication, and URL filtering only.

    I am not noticing any issues, so far, with my users and the proxy. But there are quite often "function="ssl_raw_read" file="ssl.c" line="816" message="SSL_ERROR_SYSCALL: ret=-1 error=Connection reset by peer"" messages in the filtering log. 

     

    Alan, it look like the web filtering proxy service is restarting on yours. Mine was doing that as well, but for whatever reason, I ended up turning off SSL scanning...waiting....and turning it back on again. The service restarts haven't occurred again, yet.

    Almost same issue after 9.510-5 upgrade HA Cluster with web Proxy, AD SSO and HTTP scanning. http.log is fill up and appliance shut down.

    Workaround, deleted AD account and created again. Hopefully this workaround fixed this problem.
