That's my understanding of the problem too though I would hate to have to add more memory to the system just so that clamav can run. There are a couple of bugs in the clamav bug tracker that may be of relevance. See this one that talks about the fragmentation (marked invalid): https://wwws.clamav.net/bugzilla/show_bug.cgi?id=736 This one talks about the ref counting on the in-memory DB preventing the freed memory from being reused (or something along those lines): https://wwws.clamav.net/bugzilla/show_bug.cgi?id=1028 This latter bug has a fix that should see the light of day in 0.95 from the ticket comments. If I read the ticket right, this fix should prevent the memory usage from escalating to the extent it does now (my main live system currently shows RSS at 260688).
