Kim van der Riet updated QPID-8184:
-----------------------------------
Description:
Some users are experiencing difficulty recovering the store, especially when
there are a large number of queues (several thousand). The log files show the
following pattern:
{{JERR_EFP_BADEFPDIRNAME}} in which some arbitrary number which is not
divisible by 4 is being used as the EFP file size (called EFP directory in the
log), followed by a segfault:
{noformat}
May 4 18:55:00 prodrhs1l qpidd[6240]: 2018-05-04 18:55:00 [Store] warning
Linear Store: EmptyFilePool create failed: jexception 0x0d03
EmptyFilePool::fileSizeKbFromDirName() threw JERR_EFP_BADEFPDIRNAME: Bad Empty
File Pool directory name (must be 'NNNk', where NNN is a number which is a
multiple of 4) (Partition: 1; EFP directory: '9k')
May 4 18:55:00 prodrhs1l kernel: qpidd[6240]: segfault at 10 ip
00007f4219af8e19 sp 00007ffc227a6350 error 4 in
linearstore.so[7f4219ac4000+bd000]{noformat}
In the event that the random number _is_ divisible by 4, a randomly sized
directory containing no files may appear in the partition EFP.
