Bug ID: 379739
Summary: insane baloo_file (and plasmashell) 256 GB virtual
memory size
Product: frameworks-baloo
Version: 5.33.0
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Baloo File Daemon
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
I'm running Fedora 25 KDE spin on an 8GB Thinkpad T460 laptop with SSD. Its fan
got loud, so I ran htop, found Firefox at 99% CPU, and closed it. But I noticed
some insane VIRT(ual memory sizes) for plasmashell and baloo_file, 261G and
256G! The output of `top` is below (.255 terabytes of virtual memory!), you can
see the laptop has plenty of RAM free and isn't even swapping. baloosearch
works fine.
I futzed around in /proc/<pid_of_baloo_file> and in /proc/1454/smaps I found a
possible smoking gun:
7f6150000000-7fa150000000 r--s 00000000 fd:03 133792
/home/spage/.local/share/baloo/index
Size: 268435456 kB
Rss: 667868 kB
That 268 GB size for baloo/index is obviously wrong (it's bigger than my entire
SSD), its actual size is 684468K. The plasmashell process's smaps file has a
similar entry for baloo_index, same huge size. balooctl reports the right size:
% balooctl status
Baloo File Indexer is running
Indexer state: Indexing file content
Indexed 290638 / 290638 files
Current size of index is 668.43 MiB
Bug 378749 seems similar, but doesn't mention the baloo_file process.
Maybe this is related to bug 371878 . It might suggest a bug in the way
baloo_file and plasmashell handle the baloo_index file is handled. Or it could
be a meaningless glitch. I've never created a .255 terabyte process before :-)
