RSyslog core dumped in Xen Server 8

Andre Ferreira


I'm having a problem with RSyslog in XenServer 8.


Logs are not being generated and RSyslog is Segfaulting. After some digging, I found the reason: Xen is adding the following lines to /etc/rsyslog.d/xenserver.conf,

$IMUXSockRateLimitInterval 0
$SystemLogRateLimitInterval 0

*.* ~


If I comment them out, RSyslog starts and works fine. But if I change the location of the log in XenCenter (from local to remote or vice-versa), the last line is added again. The problem is that '~' action is deprecated and no longer supported (see https://bugzilla.redhat.com/show_bug.cgi?id=1057806 and https://www.rsyslog.com/doc/v8-stable/compatibility/v7compatibility.html, among others). Xen should be using the 'stop' (*.* stop) action instead. Since it's using the deprecated command, rsyslog is segfaulting.


Did somebody else see this? Any suggestions?


Thank you,


Roberto Greiner



I'm running XenServer 8.0 upgraded from XenServer 6.5, with patches installed up to XS80E006 in a Pool with 3 Dell servers, ranging from 20GB RAM do 48GB. All VMs are in SR, some using iSCSI, some NFS.
