Session Cache is not configured [hint: SSLSessionCache]
« on: September 08, 2023, 04:21:24 AM »
Hi,

Any advice on fixing this issue appreciated.

[Fri Sep 08 04:06:59.386698 2023] [ssl:warn] [pid 14456:tid 140467374864256] AH01873: Init: Session Cache is not configured [hint: SSLSessionCache]

I tried a fix from another topic by enabling:

LoadModule socache_memcache_module modules/mod_socache_memcache.so

In: / usr / local / apache / conf / httpd.conf

Try this module:
Code: [Select]
LoadModule socache_shmcb_module modules/mod_socache_shmcb.soand in /usr/local/apache/conf/extra/httpd-ssl.conf add this line:
Code: [Select]
SSLSessionCache "shmcb:logs/ssl_scache(512000)"Restart Apache.

@overseer

The second module is already active

#   Inter-Process Session Cache:
#   Configure the SSL Session Cache: First the mechanism
#   to use and second the expiring timeout (in seconds).
#SSLSessionCache         "dbm:/usr/local/apache/logs/ssl_scache"
SSLSessionCache        "shmcb:/usr/local/apache/logs/ssl_scache(512000)"
SSLSessionCacheTimeout  300

That is the default CWP configuration, so it's good to know you haven't manually changed anything to deviate. How about if you manually create the cache file:
touch / usr / local / apache / logs / ssl_scache
Then you may want to rotate or truncate the access_log and (especially) error_log so as to reduce the file size and noise, to keep it current:
Code: [Select]
truncate -s0 / usr / local / apache/ logs / access_log
truncate -s0 / usr / local/ apache / logs/ error_log
Restart Apache and watch for your error again. (I was seeing about ~5 instances a day recently.) But do notice that it's just a warning, so not overly concerning.

Note: Of course, delete the spaces in the paths above -- the forum doesn't like some system paths being referenced in posts ;)

Ok done, error log is now cleared, I'll check it again in a while.

BTW I was in / etc / httpd / logs / ssl_error_log
But all I can find is: /etc / httpd_bak / logs, there's no / etc / httpd/

Is that another issue and should I create httpd directory and delete that httpd_bak ?

Other than these messages, the server Apache error log looks pretty clean.
