I see this in my journal, quite a bit, recently: Mar 19 09:42:37 localhost audispd[803]: queue is full - dropping event Mar 19 09:42:37 localhost audispd[803]: queue is full - dropping event Mar 19 09:42:37 localhost audispd[803]: queue is full - dropping event Mar 19 09:42:37 localhost audispd[803]: queue is full - dropping event Mar 19 09:42:37 localhost audispd[803]: queue is full - dropping event Mar 19 09:42:37 localhost audispd[803]: queue is full - dropping event This a) should not be happening and b) if you get enough to clog up your own queue, is it really a good idea to clog up the journal as well ?
The problem is that the system is being flooded by events, which is not the normally operating condition of the system. This can happen, for example, when selinux policy changes or a major upgrade of a program causes a lot of AVC's before policy is updated. The solution is to find the root cause of the flood of events and fix that by example, relabling the disk. aureport --start today --summary --event -i would help to figure out what kind of event is flooding the system.
Also, in double checking the code...it looks like this message is not limited like the other warnings. They normally stop after about 10 messages. I'll add that logic to audispd so that its consistent with other parts of the audit system.
Limit added in upstream commit 1070.
