Hello. I try to test clamav 0.90.2 on current and got strange errors: LibClamAV Warning: Multipart/alternative MIME message contains no boundary header LibClamAV Warning: Multipart/ZZZZZZZZZZZZÇÇÇÇÀå MIME message contains no boundary header LibClamAV Warning: Multipart/related MIME message contains no boundary header And sometimes clamd segfaults. $ uname -a FreeBSD clam-test2 7.0-CURRENT FreeBSD 7.0-CURRENT #1: Thu Apr 19 13:37:17 MSD 2007 citrin@clam-test2:/usr/obj/usr/src/sys/TEST amd64 $ fgrep Multiprocessor /var/run/dmesg.boot FreeBSD/SMP: Multiprocessor System Detected: 8 CPUs $ ls -l /etc/malloc.conf lrwxr-xr-x 1 root wheel 2 19 ÁÐÒ 15:12 /etc/malloc.conf -> AJ This Warnings issued randomly and it looks like race condition. This problem occurred only when running two or more clamdscan processes in parallel. With one process no warnings on same test messages. Also on same hardware, same test messages, same clamav version, but on 6.2-STABLE (where old malloc) no errors even when running 30 clamdscan processes in parallel. Any suggestions to debug this problem? -- WBR, Anton Yuzhaninov.
