Dear all, at KIT we are experiencing the following problem: on two servers, xrootd crashes all the time within minutes (usually <5 minutes) after restart. The traceback always reads: > (gdb) where > #0 0x00000000004226da in XrdOucHash_Item<char>::Next (this=0x3e2) at > ../XrdOuc/XrdOucHash.hh:55 > #1 0x00000000004227ea in XrdOucHash<char>::Purge (this=0x4a3c5550) at > ../XrdOuc/XrdOucHash.icc:190 > #2 0x00002aaaab183747 in XrdxFtsOfs::FSctl (this=<value optimized > out>, cmd=<value optimized out>, args=@0xa7847a8, error=@0x4a3c5700, > client=<value optimized out>) at > /tmp/xrootd-rpm/xrdinstall/usr/local/xrootd/include/xrootd/XrdOuc/XrdOucHash.hh:169 > #3 0x00000000004325fb in XrdXrootdProtocol::do_Qopaque > (this=0x2aaab00bcc10, qopt=32) at XrdXrootdXeq.cc:1367 > #4 0x0000000000438ead in XrdXrootdProtocol::do_Query > (this=0x2aaab00bcc10) at XrdXrootdXeq.cc:1428 > #5 0x000000000042bffb in XrdXrootdProtocol::Process2 > (this=0x2aaab00bcc10) at XrdXrootdProtocol.cc:423 > #6 0x000000000042c613 in XrdXrootdProtocol::Process > (this=0x2aaab00bcc10, lp=0x2aaab00f1ce8) at XrdXrootdProtocol.cc:328 > #7 0x000000000043e4a2 in XrdLink::DoIt (this=0x2aaab00f1ce8) at > XrdLink.cc:415 > #8 0x0000000000443811 in XrdScheduler::Run (this=0x66ffa0) at > XrdScheduler.cc:289 > #9 0x000000000044383d in XrdStartWorking (carg=0x66ffa0) at > XrdScheduler.cc:70 > #10 0x0000000000458a7b in XrdSysThread_Xeq (myargs=0xb8f1ec0) at > XrdSysPthread.cc:86 > #11 0x00000036a96064a7 in start_thread () from /lib64/libpthread.so.0 > #12 0x00000036a8ed3c2d in clone () from /lib64/libc.so.6 I have uploaded a dump to http://www-ekp.physik.uni-karlsruhe.de/~jung/core.13189; we are using xrootd version 2.9.1 build 20100510-1509. Could you please have a look at it and help us to find the cause? Thank you very much.
