It's quite possible that when icap is enables, squid must reserve some memory for icap i/o buffers. Although only one buffer may be teoretically needed, it's possible that squid uses two of them. the user memory highly depends on number and size of the uncached objects being accessed (i think cached objects aren't re-checked, are they?) -- Matus UHLAR - fantomas, uhlar@xxxxxxxxxxx ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
