Re: cachesize does not exceed 1000 entries

["Pierangelo Masarati" <ando@sys-net.it>]

First of all, I suggest you try 2.3.6: there have been considerable work
in the area of the proxies, and some more is expected for 2.3.7.  Likely,
some of the issues you're seeing may have already gone.

Do you mean that the proxies, without pcache, return more that 1000 entries?

I note that, as of 2.2, "sizelimit" is a wrapper around the "limits"
command, which is per-database, while "sizelimit" should be global, so I
suspect you should place "sizelimit" before any database statement; I need
to check.

I Note that you shouldn't use back-meta if you're proxying a single
target; however, the behavior you see shouldn't occur.  I'll try to
reproduce it and, in case, you should file an ITS.  I'll be back.
