Hi, just discovered very interesting issue. If there is a system user with very big UID (80000002 in my case), then crm_report (actually 'grep' it runs) consumes too much RAM.
Relevant part of the process tree at that moment looks like (word-wrap off): USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND ... root 25526 0.0 0.0 106364 636 ? S 12:37 0:00 \_ /bin/sh /usr/sbin/crm_report --dest=/var/log/crm_report -f 0000-01-01 00:00:00 root 25585 0.0 0.0 106364 636 ? S 12:37 0:00 \_ bash /var/log/crm_report/collector root 25613 0.0 0.0 106364 152 ? S 12:37 0:00 \_ bash /var/log/crm_report/collector root 25614 0.0 0.0 106364 692 ? S 12:37 0:00 \_ bash /var/log/crm_report/collector root 27965 4.9 0.0 100936 452 ? S 12:38 0:01 | \_ cat /var/log/lastlog root 27966 23.0 82.9 3248996 1594688 ? D 12:38 0:08 | \_ grep -l -e Starting Pacemaker root 25615 0.0 0.0 155432 600 ? S 12:37 0:00 \_ sort -u ls -ls /var/log/lastlog shows: 40 -rw-r--r--. 1 root root 23360000876 Sep 8 04:36 /var/log/lastlog That is sparse binary file, which consumes only 40k of disk space. At the same time its size is 23GB, and grep takes all the RAM trying to grep a string from a 23GB of mostly zeroes without new-lines. I believe this is worth fixing, Thank you, Vladislav _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
