We plan to upgrade clamav to 0.98.6. When testing the performance of new version clamd  by sending the same email continuously,  the average time of each email handled by clamd is about 40ms same as 0.97.4. But about every 30 emails, the process time will surge to  more than 100ms.   Old version act normally.

Log file has nothing useful information. When I use gdb attach clamd,  finally gdb say something like this:     Program terminated with signal SIGKILL, killed.      The program no longer exists.
