Root cause of the issue is jbd hungs as a result of the buffer overflow.
In the beginning of the shmemBase.c:
#define MAX_IPC_PREFIX 50 /* user-specified or generated name for */
/* shared memory seg and prefix for other
IPC */
#define MAX_IPC_SUFFIX 25 /* suffix to shmem name for other IPC names */
#define MAX_IPC_NAME (MAX_IPC_PREFIX + MAX_IPC_SUFFIX)
buffer (char prefix[]) in function createStream is used to generate base
name for mutex/events, so MAX_IPC_PREFIX is not big enough.
