[peruser] SSLSessionCache not working

[Janno Sannik]

There seems to be some problem accessing SSL session cache. As long as 
keepalive is holding the child everything is ok, but if keepalive period 
ends and client reconnects then it needs to redo all SSL authentication. 
That probably explains also why SSL based pages were very slow then many 
images was on one page. Keepalive just worked around the problem.
This thing get's really annoying if user has smart card to authenticate 
itself: firefox will keep asking certificate every time keepalive dies.

Has anybody experienced similar effect?

Apache error.log
[Fri May 30 11:36:37 2008]  [warn] (13)Permission denied: Failed to 
acquire SSL session cache lock
[Fri May 30 11:36:37 2008]  [warn] (13)Permission denied: Failed to

release SSL session cache lock

Session cache conf part:

SSLSessionCache         shmcb:/var/cache/mod_ssl/scache(512000)
SSLSessionCacheTimeout  300

folder permissions are very loose for testing purposes.

mutex default was set.

server-status shows sessions, but seems like peruser just don't get to 
read them thus every time creates a new one (status seems to show 
sessions, so peruser has atleast some access to shm )
