Hi all,
after upgrading xapian I encountered the same problem as described in
ticket
#645 Read block errors after reopen()
in our setup its 100% reproducible after each reopen(). I downgraded
again and it seems the problem occurs in Version 1.2.16 and above.
in <=1.2.15 everything works fine without seeing this error once.
attaches strace shows read ends on FD.
strace starts at reopen() call.
FDs are shown on bottom
