--- Begin Message ---Package: dovecot-imapd Version: 1:2.1.7-7 Severity: normal It seems that every once in a while the imap-login process gets out of control, eating 100% CPU over multiple hours. Attaching gdb, I'm getting this: (gdb) bt #0 0x00007fffe54a5a56 in gettimeofday () #1 0x00007fee6d9f1f8a in gettimeofday () from /lib/x86_64-linux-gnu/libc.so.6 #2 0x00007fee6dd2fcb5 in io_loop_handle_timeouts () from /usr/lib/dovecot/libdovecot.so.0 #3 0x00007fee6dd30c7b in io_loop_handler_run () from /usr/lib/dovecot/libdovecot.so.0 #4 0x00007fee6dd2fa28 in io_loop_run () from /usr/lib/dovecot/libdovecot.so.0 #5 0x00007fee6dd1c483 in master_service_run () from /usr/lib/dovecot/libdovecot.so.0 #6 0x00007fee6df7e79e in login_binary_run () from /usr/lib/dovecot/libdovecot-login.so.0 #7 0x00007fee6d973ead in __libc_start_main () from /lib/x86_64-linux-gnu/libc.so.6 #8 0x00007fee6e3b0b2d in ??
