Hi,
with build 171 beta I started my IPFire Test environment on a VMware ESXI hypervisor. Looking through the logs after 1 week running time lead me to that kernel messages:
03:02:15 kernel: perf: interrupt took too long (3472 > 3360), lowering kernel.perf_event_max_samp le_rate to 57000
03:02:28 kernel: perf: interrupt took too long (4446 > 4340), lowering kernel.perf_event_max_samp le_rate to 44000
03:02:38 kernel: perf: interrupt took too long (5562 > 5557), lowering kernel.perf_event_max_samp le_rate to 35000
03:02:50 kernel: perf: interrupt took too long (6990 > 6952), lowering kernel.perf_event_max_samp le_rate to 28000
03:07:38 kernel: perf: interrupt took too long (8800 > 8737), lowering kernel.perf_event_max_samp le_rate to 22000
03:10:11 kernel: perf: interrupt took too long (11065 > 11000), lowering kernel.perf_event_max_sa mple_rate to 18000
03:15:10 kernel: perf: interrupt took too long (13846 > 13831), lowering kernel.perf_event_max_sa mple_rate to 14000
03:21:01 kernel: perf: interrupt took too long (17382 > 17307), lowering kernel.perf_event_max_sa mple_rate to 11000
03:33:57 kernel: perf: interrupt took too long (21750 > 21727), lowering kernel.perf_event_max_sa mple_rate to 9000
03:59:33 kernel: perf: interrupt took too long (27196 > 27187), lowering kernel.perf_event_max_sa mple_rate to 7000
08:52:29 kernel: perf: interrupt took too long (34090 > 33995), lowering kernel.perf_event_max_sa mple_rate to 5000
Google couldn’t tell me anything usefull about it. I checked a IPFire installation on the same host with build 169 and it has the same log entries.
What does that mean?
Thx in advance.
