for worst guess, it looks to be a side effect of page cache. But won't cause any problem except one extra popup box. I believe this side effect can be eliminated after further investigation to the php scripts or it's one normal exception which already under the scripts' consideration.
It fixed not doing that anymore. I think it was a vbseo or the admin/modcp when i change it to the real folder name. I realize I forgot a important file for vbseo as well when I upgrade it.

Not sure if the cron job is really working and thanks for all the support.
2.check each cache file's time stamp, if no too old ones, the cron job should be working fine:
#find /dev/shm/lsdiskcache -type f --exec ls --full-time {} \;
sorry, looks the blog need update. should be:
add one line at the end of /etc/crontab:
*/10 * * * * root find /tmp/diskcache -type f -mmin +8 -delete 2>/dev/null
in your case, replace above /tmp/diskcache to /dev/shm/lsdiskcache
