Can not reproduce with ulogd-2.0.4 here: # pgrep -a ulogd 1675 /usr/sbin/ulogd --daemon --uid ulogd --pidfile /run/ulogd.pid # /etc/init.d/ulogd reopen_logs * Reopening ulogd logfiles ... [ ok ] # pgrep -a ulogd 1675 /usr/sbin/ulogd --daemon --uid ulogd --pidfile /run/ulogd.pid Please increase ulogd logging verbosity to '1' via 'loglevel' option in ulogd config and perform needed steps to reproduce your problem, then attach related part of ulogd's logfile here (one that is set via option 'logfile' in config).

Your changes can be the source of your problems. For example, 'create' option could be viable. Please check if this issue is reproducible with logrotate configuration from tree.
Please also attach output of 'emerge --info ulogd' command.
Even with increased verbosity I can't find anything interesting. // aplication starts Mon Oct 13 11:18:37 2014 <5> ulogd.c:843 building new pluginstance stack: 'ulog1:ULOG,base1:BASE,ip2str1:IP2STR,print1:PRINTPKT,emu1:LOGEMU' Mon Oct 13 11:18:37 2014 <5> ulogd.c:1441 Changing UID / GID // now ulogs receives SIGHUP Mon Oct 13 11:20:04 2014 <5> ulogd.c:1260 signal received, calling pluginstances That's all in logfile. About changes in logrotate, I agree that my config is missing some options, I'm going to add them but I think that sendig SIGHUP (without rotating logs) shouldn't harm ulogd. # emerge --info ulogd Portage 2.2.8-r2 (default/linux/amd64/13.0, gcc-4.7.3, glibc-2.19-r1, 3.14.14-gentoo x86_64) ================================================================= System Settings ================================================================= System uname: Linux-3.14.14-gentoo-x86_64-Intel-R-_Xeon-R-_CPU_3065_@_2.33GHz-with-gentoo-2.2 KiB Mem: 2052476 total, 358880 free KiB Swap: 2097148 total, 2097148 free Timestamp of tree: Wed, 08 Oct 2014 10:00:01 +0000 ld GNU ld (GNU Binutils) 2.23.2 app-shells/bash: 4.2_p53 dev-lang/perl: 5.18.2-r1 dev-lang/python: 2.7.7, 3.3.5-r1 dev-util/pkgconfig: 0.28-r1 sys-apps/baselayout: 2.2 sys-apps/openrc: 0.12.4 sys-apps/sandbox: 2.6-r1 sys-devel/autoconf: 2.69 sys-devel/automake: 1.12.6, 1.13.4 sys-devel/binutils: 2.23.2 sys-devel/gcc: 4.7.3-r1 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4.2-r1 sys-devel/make: 4.0-r1 sys-kernel/linux-headers: 3.13 (virtual/os-headers) sys-libs/glibc: 2.19-r1 Repositories: gentoo ACCEPT_KEYWORDS="amd64" ACCEPT_LICENSE="* -@EULA" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-O2 -pipe -march=native" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/env.d /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -pipe -march=native" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs collision-protect config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="http://distfiles.gentoo.org" LANG="en_US.UTF-8" LC_ALL="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j3" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_EXTRA_OPTS="-O" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --omit-dir-times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="" USE="acl amd64 bash-completion bcmath bzip2 cli cracklib crypt curl cxx device-mapper dri exif fortran ftp glibc-omitfp hpn iconv idn ipv6 mmx modules multilib ncurses nls nptl openmp pam pcre readline session slang sockets sse sse2 sse3 ssl ssse3 unicode zip zlib" ABI_X86="64" ALSA_CARDS="ali5451 als4000 atiixp atiixp-modem bt87x ca0106 cmipci emu10k1x ens1370 ens1371 es1938 es1968 fm801 hda-intel intel8x0 intel8x0m maestro3 trident usb-audio via82xx via82xx-modem ymfpci" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump author" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ublox ubx" INPUT_DEVICES="keyboard mouse evdev" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LINGUAS="en" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-5" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7 python3_3" RUBY_TARGETS="ruby19 ruby20" USERLAND="GNU" VIDEO_CARDS="fbdev glint intel mach64 mga nouveau nv r128 radeon savage sis tdfx trident vesa via vmware dummy v4l" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, SYNC, USE_PYTHON ================================================================= Package Settings ================================================================= app-admin/ulogd-2.0.3 was built with the following: USE="nfct nflog -dbi -doc -mysql -nfacct -pcap -postgres -sqlite" ABI_X86="64" CFLAGS="-march=native -O2 -ggdb -pipe" CXXFLAGS="-march=native -O2 -ggdb -pipe" Ok, I think I found what makes problem, strace shows: #
