Ciao, as instructed by CMS, we changed on all our nodes the monitoring endpoint from

xrootd.monitor all auth flush 30s mbuff 1472 window 5s dest files io info redir user xrootd.t2.ucsd.edu:9930

xrootd.monitor all fstat 60s lfn ops ssq xfr 5 ident 5m dest fstat info user CMS-AAA-EU-COLLECTOR.cern.ch:9330

after than, a few of us noticed that both in redirectors and in site-redirectors we get a xrootd crash minutes after the start (we understand that configuration is probably unneeded on a redir, but many of us still have it for config consistency).

no output from the crash, just lines like

Nov 5 09:30:09 xrootd-redic kernel: [17619227.751667] xrootd[8524]: segfault at 8 ip 0000000000417743 sp 00007f2089c06cc0 error 6 in xrootd[400000+30000]

in the /var/log/messages

It does not seem to be a collector problem, indeed if we put

xrootd.monitor all auth flush 30s mbuff 1472 window 5s dest files io info redir user CMS-AAA-EU-COLLECTOR.cern.ch:9330

all is ok

is it a t-stream vs f-stream problem?

my xrootd version is

[root@xrootd-redic xrootd]# rpm -qa|grep xrootd
xrootd-client-libs-3.3.6-1.slc6.x86_64
xrootd-3.3.6-1.slc6.x86_64
xrootd-client-3.3.6-1.slc6.x86_64
xrootd-libs-3.3.6-1.slc6.x86_64
xrootd-server-libs-3.3.6-1.slc6.x86_64

(not sure about the other cases...)

and the config says

all.role manager

thanks!

tom
