Anyway, does this > die right at startup or does it run for a while then crash? It runs for a while, which makes it so much harder to debug it. It also kills the cmsd with the same error message. (the messages are from /var/log/xrootd/xrootd.log and cmsd.log. I haven't set up the box, I just compiled the software and just happens to be awake. I think I managed to change the settings to enable coredumps now, hopefully I can get something out of it. > Andy > > On Sat, 18 Oct 2014, Ulf Tigerstedt wrote: > >> Our box is a bit unstable, with xrootd dying: >> >> >> 141018 03:09:02 2391 Copr. 2004-2012 Stanford University, xrd version >> v4.0.3 >> *** stack smashing detected ***: /usr/bin/xrootd terminated >> ======= Backtrace: ========= >> /lib64/libc.so.6(__fortify_fail+0x37)[0x7f0740eb58f7] >> /lib64/libc.so.6(__fortify_fail+0x0)[0x7f0740eb58c0] >> /lib64/libXrdUtils.so.2(+0x2a124)[0x7f0741fda124] >> /lib64/libXrdUtils.so.2(_ZN12XrdSysLogger8zHandlerEv+0xa8)[0x7f0741fdae18] >> >> /lib64/libXrdUtils.so.2(_Z14XrdSysLoggerRTPv+0x1a)[0x7f0741fdb15a] >> /lib64/libXrdUtils.so.2(XrdSysThread_Xeq+0x37)[0x7f0741fd3107] >> /lib64/libpthread.so.0(+0x7df3)[0x7f0741b97df3] >> /lib64/libc.so.6(clone+0x6d)[0x7f0740e9e01d] >> ======= Memory map: ======== >> >> >> soo.. xrootd is having buffer overflows? >> >> xrootd is from epel7, the FAX stuff I compiled myself from srpms >> provided by the FAX team. >> Does anyone have suggestions what to do?
