I have a Xcache configured like this: all.export / ofs.osslib libXrdPss.so pss.origin = xrootd.async nosf pss.cachelib libXrdFileCache.so oss.localroot /tmp/data all.adminpath /tmp/xrootd/var/spool all.pidpath /tmp/xrootd/var/run The storage has a file fully cache when Xcache run under xrootd 4.12.1. When I change to use xrootd 5rc4, and access the same file, it crashed. here is the trace out. Did I miss something? $ gdb /u/sf/yangw/xrd/git/xrdgithead/amd64_rhel70/src/xrootd /tmp/yangw/core.79902 ... #0 0x00007fcb53201387 in raise () from /lib64/libc.so.6 #1 0x00007fcb53202a78 in abort () from /lib64/libc.so.6 #2 0x00007fcb531fa1a6 in __assert_fail_base () from /lib64/libc.so.6 #3 0x00007fcb531fa252 in __assert_fail () from /lib64/libc.so.6 #4 0x00007fcb4c3e9b20 in XrdPfc::Info::CompactifyAccessRecords (this=0x12a8a18) at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/XrdPfc/XrdPfcInfo.cc:380 #5 0x00007fcb4c3e9362 in XrdPfc::Info::Write (this=0x12a8a18, fp=0x1262820, fname="<unknown>") at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/XrdPfc/XrdPfcInfo.cc:290 #6 0x00007fcb4c3db0a6 in XrdPfc::File::Sync (this=0x12a8a00) at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/XrdPfc/XrdPfcFile.cc:980 #7 0x00007fcb4c3bb353 in (anonymous namespace)::DiskSyncer::DoIt (this=0x1310cc0) at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/XrdPfc/XrdPfc.cc:522 #8 0x00007fcb54499b66 in XrdScheduler::Run (this=0x61bde0 <XrdGlobal::Sched>) at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/Xrd/XrdScheduler.cc:382 #9 0x00007fcb54498c9a in XrdStartWorking (carg=0x61bde0 <XrdGlobal::Sched>) at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/Xrd/XrdScheduler.cc:88 #10 0x00007fcb544450a6 in XrdSysThread_Xeq (myargs=0x12354e0) at /u/sf/yangw/xrd/git/xrdgithead/xrootd/src/XrdSys/XrdSysPthread.cc:86 #11 0x00007fcb53fc7ea5 in start_thread () from /lib64/libpthread.so.0 #12 0x00007fcb532c98dd in clone () from /lib64/libc.so.6 -- You are receiving this because you are subscribed to this thread.
