https://bugzilla.balabit.com/show_bug.cgi?id=208 Anton <koldaevav@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|FIXED | Status|RESOLVED |REOPENED --- Comment #14 from Anton <koldaevav@gmail.com> 2012-10-31 14:33:19 --- Unfortunately I'm seeing almost the same problem even with updated version(3.3.7). Looks like I'm not able to reproduce it this time on my test server but in production I see syslog-ng consumes all the memory again. It stops writing any logs right after enabling debug. The process of memory consumption about 3x slower than without this bugfix.
