Vladislav, Ged:
Reloading select databases is not feasible at this time, because signatures are
loaded into the same structures in memory and that entire thing is recreated on
reload.
Regarding the threaded reload feature ( ticket:
https://bugzilla.clamav.net/show_bug.cgi?id=10979 )...
The main reason the "threaded reload" patch is held back at present is
primarily because the recent work and interest in the patch came at the same time that
0.102 development was in code freeze while we tested and applied bug fixes for release.
Reloading in a separate thread means that the memory usage will double (going from
roughly ~750MB to ~1500MB) during the reload before it frees the original signatures and
drops back to ~750MB.
We already have many complaints about freshclam and clamd memory usage, and
this change in behavior could cause trouble for some users, so we want to
provide an option to reload the traditional way. That's the second reason why
the patch isn't been merged for 0.103 yet. We have to dedicate some time to
code the ability to reload either way. It is absolutely on our to-do list.
Great to hear work is ongoing.
I've switched to patched 0.104 just this hour.
I can easily deal with higher memory usage, but loss of service for 1-3
minutes is much harder to deal with.
Thanks!
