No, the error message is:
fatal: shared lock active/9978637B4A
Where active/9978637B4A is the relative pathname of the queue file.

Process 26515 got a shared lock, process 24516 got no lock, and
process 24519 got a shared lock.
Check your kernel parameters. Perhaps your OS has a very limited
number of locks available. This may be the result of very cheap
shared hosting.
