"Cache rebuild is already started, please wait" every fresh rebuild

[justvovus]

After installing of last Lite Commerce version and some time of its using, I'm getting the following message for every try of cache update:

ERROR: "-1" (code N/A)

Cache rebuild is already started, please wait

It happens even after cleanup in var/run and manually removing of cache rebuild locks (according to sources). Also I noticed that cache is rebuilded even after such error.

You should also delete file var/.rebuildStarted

It's autoremoved when error appears.

It seems other visitors open your site while you run the cache generating routine. Try to do the following:

1. Close your site with http-authorization
2. Remove var/run and var/.rebuildStarted
3. Open any site page
4. Remove http-authorization

This should help.

Yeah, it helped. Thanks.
Strange, because I'm only one user, site is in development and in a intranet.
