I run Squid 1.NOVM.20 with your retry patch from 21 January 1998.
I see also a growing memory usage. It's only cachemgr.cgi that's wrong.
top shows the correct value.
If i remember correctly it is since 1.x.19, and it was with and without
the retrypatch. But my squid is now up for about 22 days and it has 340 Mb
in use now according to cachemgr and 38 Mb according to top.
But since i cannot discover any slowdown....why should i worry about this
at this moment ;-)

Solaris 2.4 with 96 MB RAM and 3,2 Gb cache.
