Package: dovecot-core Version: 1:2.2.27-3+deb9u5 Severity: normal Dear Maintainer,
* What led up to the situation? When I try to use the command 'dovecot dump username', it just hang and unkillable by CTRL-C. Finally need to reboot to get rid of it. * What exactly did you do (or not do) that was effective (or ineffective)? # jobs -l [1]+ 2447 Running doveadm dump username 2448 Running | grep 'ref.*\b0\b' & (wd: /home) # strace -p 2447 strace: Process 2447 attached futex(0x5622aae21730, FUTEX_WAIT_PRIVATE, 2, NULL <--hanging here Thanks. -- Package-specific info: dovecot configuration --------------------- # 2.2.27 (c0f36b0): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.16 (fed8554) # OS: Linux 4.15.18-21-pve x86_64 Debian 9.12 auth_username_format = %Ln mail_location = mdbox:~/mdbox namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = " imap lmtp" service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = # hidden, use -P to show it userdb { driver = passwd } -- System Information: Debian Release: 9.12 APT prefers oldstable-updates APT policy: (500, 'oldstable-updates'), (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 4.15.18-21-pve (SMP w/2 CPU cores) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968), LANGUAGE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages dovecot-core depends on: ii adduser 3.115 ii init-system-helpers 1.48 ii libbz2-1.0 1.0.6-8.1 ii libc6 2.24-11+deb9u4 ii libexttextcat-2.0-0 3.4.4-2+b1 ii liblz4-1 0.0~r131-2+b1 ii liblzma5 5.2.2-1.2+b1 ii libpam-runtime 1.1.8-3.6 ii libpam0g 1.1.8-3.6 ii libssl1.1 1.1.0l-1~deb9u1 ii libstemmer0d 0+svn585-1+b2 ii libwrap0 7.6.q-26 ii lsb-base 9.20161125 ii openssl 1.1.0l-1~deb9u1 ii ucf 3.0036 ii zlib1g 1:1.2.8.dfsg-5 dovecot-core recommends no packages.
