[systemd-devel] Journald - heap size

[Christian Häßelbarth]

Hi all,

I'm using systemd in version 197.
I've observed that the heap size of the journald continuously grows.

I used "cat /proc/[PID_OF_JOUNALD]/smaps for observing the heap size.

Right after starting the heap size is about 772 kB

10041000-10102000 rwxp 00000000 00:00 0          [heap]
Size:                772 kB
Rss:                 652 kB
Pss:                 652 kB
Shared_Clean:          0 kB
Shared_Dirty:          0 kB
Private_Clean:         0 kB
Private_Dirty:       652 kB
Referenced:          652 kB
Anonymous:           652 kB
AnonHugePages:         0 kB
Swap:                  0 kB
KernelPageSize:        4 kB
MMUPageSize:           4 kB
Locked:                0 kB


After 7 days of operation the heap size is about 6272 kB

10041000-10102000 rwxp 00000000 00:00 0          [heap]
Size:                6272 kB
Rss:                 6172 kB
Pss:                 6172 kB
Shared_Clean:          0 kB
Shared_Dirty:          0 kB
Private_Clean:         0 kB
Private_Dirty:       6172 kB
Referenced:          6172 kB
Anonymous:           6172 kB
AnonHugePages:         0 kB
Swap:                  0 kB
KernelPageSize:        4kB
MMUPageSize:           4kB
Locked:                0 kB

My journald.conf is the following

[Journal]
Storage=none
#Compress=yes
#Seal=yes
#SplitMode=login
#RateLimitInterval=10s
#RateLimitBurst=200
#SystemMaxUse=
#SystemKeepFree=
#SystemMaxFileSize=
#SystemMinFileSize=
#RuntimeMaxUse=1M
#RuntimeKeepFree=
#RuntimeMaxFileSize=
#RuntimeMinFileSize=
#ForwardToSyslog=yes
#ForwardToKMsg=no
#ForwardToConsole=no
#TTYPath=/dev/console
#MaxLevelStore=debug
#MaxLevelSyslog=debug
#MaxLevelKMsg=notice
#MaxLevelConsole=info


Is it a known bug in version 197?

Thanks for clearification and help!

Regards
Christian
