We used memcache as a session storage server because we needed to
balance load across servers and share session data. Persistent file
storage is not usable, and since memcache session storage is easy to
configure in PHP, so we have decided to use it.
Before this, memcache maximum storage was set to 64 MB, the data went
up to 54 MB and so we thought it was the cause of cache misses. But
after we increased to 256 MB, the problem is still occurring. Users
report that after they logged in, they click on another page and they
get logged out. But after a refresh they appear logged in again.

As far as i can see, nobody has asked this questions before: if you want to use memcached
as a session store, how is your setup designed? specialised memcached's (good, good, good)
or one instance per webserver (bad, bad, bad)? how does your php.ini look like (all
entries starting with "session")? Do you have a any or even a large number of evictions on
your memcached's? Is your network saturated (using memcached as a session store produces a
large amount of network traffic, which can lead to connection problems, which could also
explain your issue).
Kind regards,
