Hi Ambrose,
  I guess you are leaking filedescriptors.
A clue why it happens may be in the cachemgr.
Does your build include the "squidclient" binary? It can be used to
directly acccess the cachemanager interface
squidclient -U <useername> -P <the password set in cachemgr_passwd
option> mgr:filedescriptors

should do the trick: that tool includes a description of what the
filedescriptor is being used for.

I am currently trying to build a squid for MacOS; I am not
successfully able to build rock store. Are you able to? Would you mind
sharing what options and environment you are using? Thanks!

Seems unlikely. Let's first get the facts out of cachemgr, then we can
speculate on the causes :)
