Hi, I just upgraded from 2.10 -> 2.12 and have encountered this issue while running my usual script. Console output : --------------- <pre> + lttng_msg=-q + session_cfg_path=/tmp/lttng_session_cfg + lttng -q save --force --output-path=/tmp/lttng_session_cfg session_trace + exit_status=0 + '[' 0 -eq 0 ']' + lttng -q stop session_trace + lttng -q destroy session_trace + sleep 1 + rm -rf '/var/log/lttng/shm/save/*' /var/log/lttng/shm/current + df /pramfs -h Filesystem Size Used Avail Use% Mounted on /dev/pmem0 488M 2.7M 456M 1% /pramfs + lttng -vvv load --input-path=/tmp/lttng_session_cfg DEBUG3 - 13:51:54.740354470 [3561/3561]: URI string: file:///var/volatile/tmp/lttng_session_cfg (in uri_parse() at lttng-tools/2.12.0-r0/git/src/common/uri.c:298) DEBUG3 - 13:51:54.740476330 [3561/3561]: URI file destination: /var/volatile/tmp/lttng_session_cfg (in uri_parse() at lttng-tools/2.12.0-r0/git/src/common/uri.c:335) DEBUG3 - 13:51:54.740498090 [3561/3561]: URI dtype: 3, proto: 0, host: , subdir: , ctrl: 0, data: 0 (in uri_parse() at lttng-tools/2.12.0-r0/git/src/common/uri.c:512) DEBUG1 - 13:51:54.745829510 [3561/3561]: LSM cmd type : 49 (in send_session_msg() at lttng-tools/2.12.0-r0/git/src/lib/lttng-ctl/lttng-ctl.c:143) DEBUG1 - 13:51:54.746218790 [3561/3561]: LSM cmd type : 25 (in send_session_msg() at lttng-tools/2.12.0-r0/git/src/lib/lttng-ctl/lttng-ctl.c:143) DEBUG1 - 13:51:54.746497020 [3561/3561]: LSM cmd type : 40 (in send_session_msg() at lttng-tools/2.12.0-r0/git/src/lib/lttng-ctl/lttng-ctl.c:143) *Error: Failed to load session session_trace: Not enough memory* DEBUG1 - 13:51:54.746995900 [3561/3561]: LSM cmd type : 17 (in send_session_msg() at lttng-tools/2.12.0-r0/git/src/lib/lttng-ctl/lttng-ctl.c:143) DEBUG1 - 13:51:54.747147820 [3561/3561]: LSM cmd type : 24 (in send_session_msg() at lttng-tools/2.12.0-r0/git/src/lib/lttng-ctl/lttng-ctl.c:143) DEBUG1 - 13:51:54.747353630 [3561/3561]: *epoll set max size is 1024860* (in compat_epoll_set_max_size() at lttng-tools/2.12.0-r0/git/src/common/compat/compat-epoll.c:346) *Error: Not enough memory* DEBUG1 - 13:51:54.748448160 [3561/3561]: Clean exit (in clean_exit() at lttng-tools/2.12.0-r0/git/src/bin/lttng/lttng.c:152) </pre> -------------- Has anyone encountered a similar issue?
